Tanesha has a piece of yarn that is Eight-ninths of an inch long. She cuts Five-ninths of an inch off the string.

How long is the remaining piece?

Answer: 3/9 of an inch long remaining on the piece of string.

Step-by-step explanation: For this problem we will subtract 8/9 from 5/9, since Tanesha cuts five-ninths of an inch off the string, when the string is eight-ninths of an inch long.

8/9 - 5/9 = 3/9 of an inch long remaining on the piece of string.

You basically are subtracting the numerators, top of the fraction, and keeping the denominator, bottom of the fraction, the same.
