Mr. Barber uses 7/9 yard of wire to put up a ceiling fan. He uses 1/3 yard of wire to fix a switch How much more wire does he use to put up the fan than to fix the switch

Answer 1

1/3 is the same as 3/9. To solve this, subtract 3/9 from 7/9.

$\frac{7}{9}-\frac{3}{9}= \frac{4}{9}$

Your answer is $\frac{4}{9}$
