Question

If 40% of a number is equal to two-third of another number,what is the ratio of first number to the second number?

Answer 1

Ans.

Let, the numbers are x and y.

Then 40% of x is
$\frac{40}{100} x \\ = \frac{2}{5} x$

Given that
$\frac{2}{5} x = \frac{2}{3} y \\ or \: \: \frac{x}{y} = \frac{5}{3}$


Hence, x : y = 5 : 3.

:)))I HOPE THAT THIS HELPS YOU.(((:

Answer 2

If first no is x and other no is y , then

x*40/100 = y*2/3
x/y = 2*100/120 = 200/120 = 5/3

so ratio is 5:3 ......
