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

42
Correct. The smallest number is 42.
Easiest way:
let the two numbers be 7x and 9x,
but 9x = 54
x = 6
so the smallest number, being 7x , is 42
