Answer 2

Answer:

Hi there mate!!

let me help you

see, your question is very simple. whenever we are asked to take out a number like this in the question, we will take it as a number x.

so, let the number be x

A.T.Q.(ACCORDING TO THE QUESTION)

if 9/5 of x= 45

find 2/5 of x

first find 9/5 of x =45

that is:-

9/5 × x = 45

x= 45 × 5/9

x= 5 ×5

x =25

if x= 25, then

2/5 × 25= 2× 5 = 10

:. 2/5 of x is 10
