Question

(a) 22 is 55% of what?(b) What percent of 56 is 42?

Answer 1

(a) 22 is 55% of 40.

We can multiply 22 by 0.55 to find that 22 is 55% of 40.

(b) 42 is 75% of 56.

To find this, we can start by acknowledging 50% of 56, which is 28 because it’s half of 56. We know 28 + 28 = 56, so we can split 28 in half to find that:

28 + 14 = 42, so 42 is 75% of 56.

42 + 14 = 56, which is 100%.

(a) 22 is 55% of 40.
(b) 42 is 75% of 56.

Answer 2

a)

Given:

The objective is to find 55% of what number is 22.

Step-by-step explanation:

Consider the unknown number as x.

Then, the value of x can be calculated as,

`(55)/(100)x=22\text{ . . . . (1)}`

On further solving the equation (1),

`\begin{gathered} x=22*(100)/(55) \\ x=40 \end{gathered}`

Thus, the obtained value of x is 40.

Hence, 22 is 55% of 40.
