Question

Jennifer bought a piece of wire for a crafts project that was 8/9 of a yard

long. She used 1/2 of a yard. How long was the wire she had left?

15/9 yard

7/7 yard

7/36 yard

7/18 yard

Answer 1

7/18! This is because if you double both the top and bottom of 8/9 you get 16/18. Half of 18 is 9. So if we use half a yard, 9/18, and we subtract it from 16/18, we get 7/18!
