Question

Three unknown numbers are in the ratio 5:6:7. Is it possible that the numbers are 20, 24 and 28? Why? Justify your answer.​

Answer 1

Answer:

If 5:6:7 is the ratio of 3 unknown numbers, then 20.24 and 28 van be the numbers

Step-by-step explanation:

Given,

The ratio of numbers = 5:6:7

That is, if a number is 5x, then the other numbers are 6x and 7x respectively

Where x is a constant

So let us take the first number 20 as 5x

That is, 5x = 20

x = 20/5 = 4

The next number 24 = 6x

x = 24/6 = 4

And the last number 28 = 7x

x = 28/7 = 4

So, here x = 4 is constant

Yes, 20, 24, and 28 are in the ratio 5:6:7
