Question

Can some one solve this fore me ty

Answer 1

u/8 = 3/12
cross multiply: 12u=24
divide both sides by 12: u=2

Answer 2

U = 2

Explanation:

`(u)/(8) = (3)/(12) \\ divide \: (3)/(12) \: by \: 3 \\ (u)/(8) = (1)/(4) \\ multiply \: both \: sides \: by \: 8 \\ \\ u = (1)/(4) * 8 \\ simplify \\ u = (8)/(4) \\ divide \: both \: sides \: by \: 4 \\ u = (1)/(2) \: or \: 2`
