Question

If 40% of a number is equal to two-thirds of another number, what is the ratio of
the first number to the second?
(a) 7:3
(b) 3:7
(c) 3:5
(d) 5:3
​

Answer 1

Step-by-step explanation:

Let 40 % of A = 2/3 B

Then 40A / 100 = 2B / 3

2A / 5 = 2B / 3

A / B = { 2 / 3 × 5 / 2 } = 5/3

A : B = 5 : 3
