CBSE Class 5 Mathematics Tenths And Hundredths Worksheet Set 04

I. Shift the decimal appropriately

Question 1(a). \(3.742 \times 10 = \underline{\hspace{3cm}}\)
Answer: \(37.42\)
In simple words: When multiplying by 10, shift the decimal point one place to the right.

Exam Tip: Count the number of zeros in the multiplier (10 has one zero) and move the decimal point that many places to the right.

Question 1(b). \(3.742 \div 10 = \underline{\hspace{3cm}}\)
Answer: \(0.3742\)
In simple words: When dividing by 10, shift the decimal point one place to the left.

Exam Tip: Division by 10 makes the number smaller, so move the decimal point to the left.

Question 1(c). \(3.742 \times 100 = \underline{\hspace{3cm}}\)
Answer: \(374.2\)
In simple words: When multiplying by 100, shift the decimal point two places to the right.

Question 1(d). \(3.742 \div 100 = \underline{\hspace{3cm}}\)
Answer: \(0.03742\)
In simple words: When dividing by 100, shift the decimal point two places to the left.
Exam Tip: Add leading zeros as placeholders when shifting the decimal past the existing digits.

Question 1(e). \(3.742 \times 1000 = \underline{\hspace{3cm}}\)
Answer: \(3742\)
In simple words: When multiplying by 1000, shift the decimal point three places to the right.

Exam Tip: Since 1000 has three zeros, move the decimal point three places to the right, removing the decimal point entirely as it reaches the end.

Question 1(f). \(3.742 \div 1000 = \underline{\hspace{3cm}}\)
Answer: \(0.003742\)
In simple words: When dividing by 1000, shift the decimal point three places to the left.

Exam Tip: Ensure you insert the correct number of placeholder zeros between the decimal point and the first significant digit.

Question II. Match these
Answer:
To convert paise to rupees, divide the amount in paise by 100 (since Re. 1 = 100 paise).
1. 7 paise = Rs.0.07
2. 20 paise = Rs.0.20
3. 98 paise = Rs.0.98
4. 25 paise = Rs.0.25
5. 50 paise = Rs.0.50
6. 10 paise = Rs.0.10
7. 75 paise = Rs.0.75
In simple words: Divide any paise value by 100 to write it as rupees with a decimal point.

Exam Tip: Always remember that two decimal places are used to represent paise when expressed in rupees.
