Question

1. The ratio of two numbers is 3 : 4 and their L. C. M. is 180. Find the numbers.
​

Answer 1

Step-by-step explanation:

Let the two numbers be 3x and 4x and HCF be x

We know that

Product of two number=Product of their LCM and HCF

So,

4x×3x=180×x

12x

2

=180x

12x=180

x=15

3x=3×15=45

4x=4×15=60

So, the answer is 45& 60

I hope this helped you.

Answer 2

Answer:

Roti if 2 numbers - 3 : 4

L.C.M of the two numbers - 180

So,

First, we need to find out the factors of 180

= 180 = 1, 2, 3, 4, 5, 6, 10, 12, 15, 18, 30, 36, 45, 60, 90 and 180.

So, next we need to find out the numbers which are in ratio of 3 : 4

So, the numbers are 3 and 4
