Question

Two numbers are in the ratio 5:3, if their sum.is 80. then what is the smallest number?​

Answer 1

Let the two numbers be 5x and 3x
5x+3x=80
8x = 80
x = 80/8
x = 10

5x = 5*10 = 50
3x = 3*10 = 30

Smallest number is 30 (ie 3x)

Answer 2

Step-by-step explanation:

twp numbers ratio=5:3

total number of ratio=5+3=8

$one \: number \: is \: \: \: 80 \times \frac{5}{8} \\ = 10 \times 5 = 50 \\ \\ and \: another \: number \: is \: \: 80 \times \frac{3}{8} \\ = 10 \times 3 \\ = 30$

the smallest number is 30.
