Question

What is the value of 20.5 divided by a whole number to make 5?

a) 2.0
b) 4.1
c) 10.2
d) 0.41

Answer 1

To find the value of a whole number that gives 5 when 20.5 is divided by it, we solve the equation 20.5 ÷ x = 5, yielding x = 4.1. Therefore, the correct answer is (b) 4.1.

Step-by-step explanation:

The question requires us to find the whole number that, when 20.5 is divided by it, gives a result of 5. To find this number, we can set up a division equation as follows:

20.5 ÷ x = 5

To solve for x, we multiply both sides of the equation by x and then divide both sides by 5, yielding:

x = 20.5 ÷ 5

By performing the division, we find:

x = 4.1

Therefore, the value of the whole number is 4.1, which means the correct answer is option (b) 4.1.
