Question

find the numbers for 8:3

Answer 1

let two numbers x and y
8y=3x
x+y=143
x=143-y
8y=3(143-y)
8y=429-3y
11y=429
y=39
x+39=143
x= 104

Answer 2

Given that the ratio is 8 : 3

Sum of the numbers = 143

Let the two numbers be 8x and 3x

So 8x + 3x = 143

11x = 143

x = 143 / 11

x = 13

3x = 3 × 13 = 39

8x = 8 × 13 = 104

So the two numbers are 39 and 104 respectively.

Hope it helps you.

Have a good day.
