Question

The ratio between two numbers is 3 : 4 . If their H.C.F. is 15 , find the numbers .

Answer 1

Step-by-step explanation:

LCM*HCF=product of two numbers

4*LCM=3x*4x

LCM=12x²/4

LCM=3x²

LCM of 3x and 4x=12x

12x=3x²

x=4

Answer 2

Answer:

Ratio between two numbers is 3 : 4

Let the number be X

first number equal to 3x

second number equal to 4x

x = 15

First no. = 3x = 45

second no. 4x = 60

so,

45+ 60 = 105
