Two numbers are in the ratio of 7:9, the smaller number is 42, what is the larger number
If the smaller number is 42 and the ratio of the two numbers is 7:9, we can find the larger number by setting up a proportion.
Let x be the larger number.
We know that:
42/x = 7/9
To solve for x, we can cross-multiply the proportion:
42 * 9 = x * 7
378 = 7x
x = 54
Therefore, the larger number is 54.
