Tow numbers are in ratio 5:9 .If there LCM is 180 . find the number​

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

Therefore the numbers are 45 and 60.

Answer 2
