Question

Write the following proportion: 8 is to 64 as 2 is to X

Answer 1

8 over 64 is equal to 2 over x...cross multipy and that should give you 128=8x...now just divide 128 by 8 to find x...x=16

Answer 2

1 way
$\frac{8}{64} = \frac{2}{x} \\ \\ \frac{8:4}{64:4} = \frac{2}{x} \\ \\ \frac{2}{16} = \frac{2}{x}$    ⇔  x = 16

$\frac{8}{64} = \frac{2}{x}$
We multiply the cross

$8x = 2 * 64 8x = 128 x = 16$
