Two numbers in the ratio of 7:9.The largest number is 54.Find the smallest numbers

Answer 1

We can begin by setting up a proportion:

7/9 = x/54

To solve for x, we can cross-multiply:

9x = 7 * 54

9x = 378

x = 42

Therefore, the smallest number is 42.

Answer 2

42

Answer 3

Correct. The smallest number is 42.

Answer 4

Easiest way:

let the two numbers be 7x and 9x,
but 9x = 54
x = 6

so the smallest number, being 7x , is 42

Answer 5

Yes, that is a valid and quicker method to solve the problem. Well done!
