Write an equation for the word problem: katie had a ribbon that was 23 ½ inches long. after katie cut the ribbon in two pieces, she had 8 ¼ inches of the ribbon left. how much ribbon did katie cut from her original ribbon?
a. 23 ½ - r = 8 ¼
b. 23½ + 8¼ = r
c. 23½ + r = 8¼
d. 8¼ - r = 23½

A is the answer.

Katie is starting with 23 ½ inches of ribbon and removing an unspecified amount, resulting in 8 ¼ inches left. When you remove one thing from a second thing, you are subtracting the first thing from the second. The equation then equals the amount that you have leftover.

I hope this helped!
