Im helping my son to find the area of a rectangle that is 7 3/8 inches and 4 inches the height.

I need to know how to convert the fraction into a whole number.

You can't convert a fraction to a whole number. The easiest way to do this problem is to convert the fraction to a decimal. Divide the numerator by the denominator. 7 3/8 = 7.375

A = 7.375 * 4

To convert a mixed fraction like 7 3/8 into a whole number, you can follow these steps:

1. Multiply the whole number (7) by the denominator of the fraction (8): 7 * 8 = 56.
2. Add the result to the numerator of the fraction (3): 56 + 3 = 59.
3. Place the sum from step 2 over the original denominator: 59/8.

Now, you have the fraction 59/8.

However, to find the area of a rectangle, you need to multiply the length and the width. In your case, the length of the rectangle is 7 3/8 inches (or 59/8 inches) and the height is 4 inches. So, to find the area:

Area = length * height
= 59/8 inches * 4 inches.

To multiply fractions, simply multiply the numerators together and the denominators together:

Area = (59/8) * 4
= (59 * 4) / (8)
= 236/8
= 29 2/3 inches.

So, the area of the rectangle is 29 2/3 inches.
