Question

The ratio of two numbers is 15:11. If their HCF is 13, then these numbers will be
(i) 15:11
(ii) 75:55
(iii) 15:77.
(iv) 195:143​

Answer 1

Answer:

195 : 143

Explanation:

hello ,

so take two number like 20 and 36

we can write this number 20 as 2*2*5 and 36 as 2*2*3*3 so hcf = 2*2

so the ratio of 20 and 36 is 5 : 9

If we want to get back our numbers from the ratio and hcf .We simply do 5*hcf and 9*hcf ie 5*4 and 9*4. We get our original numbers ie 20 and 36.

Apply the same thing to given problem.

Ratio is 15:11 ,hcf=13

So, numbers are 15*13 and 11*13 ie 195 and 143

thank you

hope it is helpful to you
