the product of three numbers is 315.if two of the numbers are 7 and 9 .what is the third number?

7 * 9 = 63

315/63 = 5
so
7 * 9 * 5 = 315

To find the third number, we can use the given information that the product of three numbers is 315 and two of the numbers are 7 and 9.

Let the third number be x.

We know that the product of three numbers is obtained by multiplying all three numbers together:

7 * 9 * x = 315

To find the value of x, we can rearrange the equation:

x = 315 / (7 * 9)

Calculating the expression gives us:

x = 315 / 63

x = 5

Therefore, the third number is 5.
