## anonymous 5 years ago Use the cross-product method to find out whether the pair of fractions is equivalent. 2/9, 4/16

1. anonymous

2*16 = 4 *9 32 = 32 cool

2. anonymous

how did you get that?

3. anonymous

$\frac{2}{9} \times \frac{4}{16}$ you multiply across the diagonals. the 2 matches with the 16 and the 9 matches with the 4.
