Remaining length = 4 cm 1 mm
Length burnt = \((10\text{ cm } 2\text{ mm}) - (4\text{ cm } 1\text{ mm})\)
\(= (10 - 4)\text{ cm } + (2 - 1)\text{ mm}\)
\(= 6\text{ cm } 1\text{ mm}\)
In simple words: Subtract the remaining length from the original length: \(10\text{ cm } 2\text{ mm} - 4\text{ cm } 1\text{ mm} = 6\text{ cm } 1\text{ mm}\).

Exam Tip: Subtract centimeters from centimeters and millimeters from millimeters separately.

Question v. Mother bought 5 kg rice, 3 kg 250 g sugar and 8 kg 100 g flour from a shop. What will be the weight of her bag?

Weight of rice = 5 kg 000 g
Weight of sugar = 3 kg 250 g
Weight of flour = 8 kg 100 g
Total grams = \(250\text{ g} + 100\text{ g} = 350\text{ g}\)
Total kilograms = \(5\text{ kg} + 3\text{ kg} + 8\text{ kg} = 16\text{ kg}\)
Total weight = 16 kg 350 g
In simple words: Add all the kilograms together and all the grams together to get 16 kg and 350 g.
