Question

Complete the ratio so it is equal 5/4= ?/16

Answer 1

`(5)/(4) = (?)/(16)`

Switch sides:


`(?)/(16) = (5)/(4)`

find least common multiplier of 16, 4

Prime factorization of 16 = 4²

Prime factorization of 4 = 2²

LCM = 16

Multiply by LCM


`(?)/(16) *16= (5)/(4)*16`


`? = 20`

hope this helps!
