SUBTOPIC :OPERATION ON DECIMALS

Q1. The product of two numbers is 2.0016. If one of them is 0.72, find the other
number.
Solution:
Product of two numbers = 2.0016
One number = 0.72
Other number = 2.0016 ÷ 0.72

Hence, the required number = 2.78.
Q2.
What is to be added to 36.85 to get 59.41?
Solution:

Let the number to be added to 36.85 to get 59.41 be x (1/2 mark)
So we have,
x + 36.85 = 59.41 (1/2 mark)
x = 59.41 - 36.85 (1/2 mark)

x =
(1/2 mark)
Therefore, x = 22.56
Hence, the number to be added to 36.85 to get 59.41 be 22.56 (1 mark)

Q3.
Divide 6.9168 by 52.4
Solution:

We have,
