Answer 1

Hey mate!

Here is your answer > >

Let 1 number be x and other number be y

According to question

40% of x=2/3×y

40/100×x=2/3×y

2/5×x=2/3×y

x/y=2/3÷2/5

x/y=2/3×5/2

x/y=5/3=5:3



Hope it helps!

Thankyou ☆ ☆

Answer 2

let the one number be x and another number be y



40% of x = 2/ 3 rd of y



0.4x = 2y/ 3

1.2x = 2y



x / y = 2 / 1.2


x/ y = 20 / 12 => x / y = 5/ 3



x : y = 5 : 3



Answer: required ratio = 5 : 3
