Question

How to find the no if their ratio and hcf are given?

Answer 1

Answer:

Write the ratio in lowest terms.

Let's say this is a/b.

Then a/b is the required ratio, but a and b have hcf = 1.

Just multiply them by the hcf you need to get the required numbers.

Example:

Given ratio is 5/7 and hcf is 3.

The ratio is lowest terms is 5/7.

So take 5 and 7, then multiply them by 3 to get...

15 and 21.

These are the required numbers.

(i.e. 15/21 = 5/7 and hcf(15,21) = 3)

Answer 2

Answer:

Step-by-step explanation:

Let the ratios be a:b

then the no.s are ax and bx where x is the HCF
