Exam Tip: Combine the converted unit with the given sub-unit.

2. Add.

Question a.
m cm
86 31
+ 10 84
Answer:
Adding centimetres: \(31 + 84 = 115 \text{ cm}\) (which is \(1 \text{ m}\) and \(15 \text{ cm}\))
Adding metres: \(86 + 10 + 1 \text{ (carried over)} = 97 \text{ m}\)
Total sum = \(97 \text{ m } 15 \text{ cm}\)
In simple words: Add cm columns and m columns separately, carrying over extra meters if cm exceeds 100.

Exam Tip: Remember \(100 \text{ cm} = 1 \text{ m}\), so carry over 1 to the metre column.

Question b.
m cm
7 78
+ 6 23
Answer:
Adding centimetres: \(78 + 23 = 101 \text{ cm}\) (which is \(1 \text{ m}\) and \(1 \text{ cm}\))
Adding metres: \(7 + 6 + 1 \text{ (carried over)} = 14 \text{ m}\)
Total sum = \(14 \text{ m } 1 \text{ cm}\)
In simple words: Add centimetres, carry over 1 metre, then add metres.

Exam Tip: Write 1 cm as 01 cm to maintain proper place values.

Question c.
km m cm
19 035 26
+ 21 975 40
Answer:
Adding cm: \(26 + 40 = 66 \text{ cm}\)
Adding m: \(035 + 975 = 1010 \text{ m}\) (which is \(1 \text{ km}\) and \(10 \text{ m}\))
Adding km: \(19 + 21 + 1 \text{ (carried over)} = 41 \text{ km}\)
Total sum = \(41 \text{ km } 010 \text{ m } 66 \text{ cm}\)
In simple words: Add each unit column from right to left, carrying over when limits are crossed.

Exam Tip: Metres column carries over to km when it reaches 1000.

Question d.
km m cm
88 706 45
+ 45 635 90
Answer:
Adding cm: \(45 + 90 = 135 \text{ cm}\) (\(1 \text{ m}\) and \(35 \text{ cm}\))
Adding m: \(706 + 635 + 1 = 1342 \text{ m}\) (\(1 \text{ km}\) and \(342 \text{ m}\))
Adding km: \(88 + 45 + 1 = 134 \text{ km}\)
Total sum = \(134 \text{ km } 342 \text{ m } 35 \text{ cm}\)
In simple words: Add cm, carry over to m, add m, carry over to km, and add km.

Exam Tip: Double check carry-over values carefully.

Question e.
kg g
16 508
8 085
+ 12 007
Answer:
Adding grams: \(508 + 085 + 007 = 600 \text{ g}\)
Adding kilograms: \(16 + 8 + 12 = 36 \text{ kg}\)
Total sum = \(36 \text{ kg } 600 \text{ g}\)
In simple words: Sum up all the grams and then sum up all the kilograms.

Exam Tip: Since total grams is less than 1000, no carry-over is needed for kg.

Question f.
kg g
96 200
+ 27 875
Answer:
Adding grams: \(200 + 875 = 1075 \text{ g}\) (\(1 \text{ kg}\) and \(075 \text{ g}\))
Adding kilograms: \(96 + 27 + 1 = 124 \text{ kg}\)
Total sum = \(124 \text{ kg } 75 \text{ g}\)
In simple words: Add grams, carry 1 kg over, and add the kilograms.

Exam Tip: 1075 g becomes 1 kg and 75 g.

Question g.
l ml
13 725
+ 42 250
Answer:
Adding millilitres: \(725 + 250 = 975 \text{ ml}\)
Adding litres: \(13 + 42 = 55 \text{ l}\)
Total sum = \(55 \text{ l } 975 \text{ ml}\)
In simple words: Add millilitres and litres columns directly.

Exam Tip: Millilitres total is under 1000, so no carry over.

Question h.
l ml
97 058
6 275
+ 0 780
Answer:
Adding millilitres: \(058 + 275 + 780 = 1113 \text{ ml}\) (\(1 \text{ l}\) and \(113 \text{ ml}\))
Adding litres: \(97 + 6 + 0 + 1 = 104 \text{ l}\)
Total sum = \(104 \text{ l } 113 \text{ ml}\)
In simple words: Sum the millilitres, carry 1 litre over, and sum the litres.

Exam Tip: Align decimal and unit columns properly before adding.

3. Subtract :

Question a.
m cm
9 38
- 3 75
Answer:
Subtracting centimetres: Since \(38 < 75\), borrow \(1 \text{ m}\) (\(100 \text{ cm}\)) from 9 m.
New cm value = \(100 + 38 = 138 \text{ cm}\)
\(138 - 75 = 63 \text{ cm}\)
Subtracting metres: \(8 - 3 = 5 \text{ m}\)
Total difference = \(5 \text{ m } 63 \text{ cm}\)
In simple words: Borrow 1 metre (100 cm) when cm is too small to subtract.

Exam Tip: Always reduce the metre column by 1 after borrowing.

Question b.
m cm
58 20
- 17 65
Answer:
Subtracting centimetres: Since \(20 < 65\), borrow \(1 \text{ m}\) (\(100 \text{ cm}\)) from 58 m.
New cm value = \(100 + 20 = 120 \text{ cm}\)
\(120 - 65 = 55 \text{ cm}\)
Subtracting metres: \(57 - 17 = 40 \text{ m}\)
Total difference = \(40 \text{ m } 55 \text{ cm}\)
In simple words: Borrow 100 cm to add to 20 cm, then subtract.

Exam Tip: Remember to subtract 1 from the upper metre digit.

Question c.
km m cm
47 900 80
- 35 430 76
Answer:
Subtracting cm: \(80 - 76 = 04 \text{ cm}\)
Subtracting m: \(900 - 430 = 470 \text{ m}\)
Subtracting km: \(47 - 35 = 12 \text{ km}\)
Total difference = \(12 \text{ km } 470 \text{ m } 4 \text{ cm}\)
In simple words: Subtract each unit column directly from right to left as top values are larger.

Exam Tip: Check if borrowing is needed before subtracting each column.

Question d.
km m cm
62 470 85
- 15 985 50
Answer:
Subtracting cm: \(85 - 50 = 35 \text{ cm}\)
Subtracting m: Since \(470 < 985\), borrow \(1 \text{ km}\) (\(1000 \text{ m}\)) from 62 km.
New m value = \(1000 + 470 = 1470 \text{ m}\)
\(1470 - 985 = 485 \text{ m}\)
Subtracting km: \(61 - 15 = 46 \text{ km}\)
Total difference = \(46 \text{ km } 485 \text{ m } 35 \text{ cm}\)
In simple words: Borrow 1000 metres from kilometres when the metre value is smaller.

Exam Tip: 1 km = 1000 m, so add 1000 to the metres column when borrowing.

Question e.
kg g
59 539
- 25 218
Answer:
Subtracting grams: \(539 - 218 = 321 \text{ g}\)
Subtracting kilograms: \(59 - 25 = 34 \text{ kg}\)
Total difference = \(34 \text{ kg } 321 \text{ g}\)
In simple words: Subtract grams and kilograms directly without borrowing.

Exam Tip: Verify that upper gram value is greater than lower gram value.

Question f.
kg g
33 125
- 19 375
Answer:
Subtracting grams: Since \(125 < 375\), borrow \(1 \text{ kg}\) (\(1000 \text{ g}\)) from 33 kg.
New g value = \(1000 + 125 = 1125 \text{ g}\)
\(1125 - 375 = 750 \text{ g}\)
Subtracting kilograms: \(32 - 19 = 13 \text{ kg}\)
Total difference = \(13 \text{ kg } 750 \text{ g}\)
In simple words: Borrow 1000 grams to make 1125 grams before subtracting.

Exam Tip: Reduce kg by 1 after borrowing.

Question g.
l ml
20 875
- 18 609
Answer:
Subtracting millilitres: Since \(875 > 609\), subtract directly: \(875 - 609 = 266 \text{ ml}\)
Subtracting litres: \(20 - 18 = 2 \text{ l}\)
Total difference = \(2 \text{ l } 266 \text{ ml}\)
In simple words: Subtract ml and l columns directly.

Exam Tip: No borrowing is needed here.

Question h.
l ml
31 250
- 29 225
Answer:
Subtracting millilitres: \(250 - 225 = 025 \text{ ml}\)
Subtracting litres: \(31 - 29 = 2 \text{ l}\)
Total difference = \(2 \text{ l } 25 \text{ ml}\)
In simple words: Subtract the millilitres and litres parts separately.

Exam Tip: Write 025 ml clearly as 25 ml.
