In m*n=225, m is a two digit number and n is a one digit number. What numbers do m represent? What numbers do n represent?

1 answer

To find the possible values of m and n, we need to find pairs of numbers whose product is 225.

The prime factorization of 225 is 3^2 * 5^2.

Since m is a two-digit number, it can be expressed as xy, where x is the tens digit and y is the units digit.

So, m = 10x + y.

Considering the pairs of factors of 225, we find the following possibilities for m and n:

1. m = 25 and n = 9
If m = 25 and n = 9, then 25 * 9 = 225, which satisfies the equation m*n = 225.

2. m = 15 and n = 15
If m = 15 and n = 15, then 15 * 15 = 225, which also satisfies the equation m*n = 225.

Therefore, m can represent the numbers 25 and 15, and n can represent the numbers 9 and 15.
