Question

4. Two numbers are in the ratio 3 : 4. If their LCM is 180, find the numbers.
Hint. Let the required numbers be 3x and 4x.
Then, their LCM is 12x.​

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

Answer:

your answer is 45 and 60
