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

`(8)/(64) = (2)/(x) \\ \\ (8:4)/(64:4) = (2)/(x) \\ \\ (2)/(16) = (2)/(x)` ⇔ x = 16

2.way

`(8)/(64) = (2)/(x)`
We multiply the cross


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