Question

The ratio of two numbers is 4:5 and their H.C.F is 3 find the first number?​

Answer 1

answer: 120

Step-by-step explanation:

We are given that The ratio of two numbers is 4:5.

Let the ratio be x

So, the numbers are 4x and 5x

The hcf of these numbers is 6

We know that :

LCMx HCF Product of two numbers

LCM X 6 = 4x x 5x

HCF of 4x and 5x is x

Since we are given that the HCf of 4x and 5x = 6

So, x = 6

So, LCM x 6 = = 4(6) × 5(6)

LCM X 6 = 24 × 30

LCM = 24 x 5

LCM = 120
