Question

The ratio of two numbers is 4:5 and their lcm is 120 then the numbers are​

Answer 1

3
$3 \frac{4}{?}$

Answer 2

the ratio = 4:5

let the ratios be x

that means 4x :5x

we know that : means division so 4x :5x

their lcm = 120

20x= 120

x = 120/20

x = 6

4 x = 4 x 6 = 24

5x = 5 × 6 = 30

i found 20 by multiplying 4 and 5
