Converting everything to inches.
I'm assuming you want your final answer to be in inches. First start off this problem by converting everything to inches to make it easier.
There are 36 inches in a yard, so to find the number of inches in a certain number of yards you would multiply the number of yards by 36 inches.
Let's start by finding the amount of inches that make up 8 yards and 7 yards. Multiply 8 yards by 36 inches and 7 yards by 36 inches, then rewrite the problem to show the converted form.
- 8 yards * 36 inches = 288 inches
- 7 yards * 36 inches = 252 inches
Now let's convert the feet on the right side of the expression. There are 12 inches in a foot, so multiply the amount of feet by 12 inches.
- 2 feet * 12 inches = 24 inches
Rewrite the problem with the converted amounts.
288 inches, 4 inches - 252 inches, 24 inches, 8 inches
Add the inches together on both sides of the equation.
292 inches - 284 inches
Subtract 284 from 292. Your final answer is:
8 inches (answer)
