Question

another question...actually m very weak in maths...:)
If Greg lost 20 pounds, then the ratio of Ted's weight to Greg's weight would be 4/3. If Ted's weighs 180 pounds what was Greg's initial weight?

Answer 1

let Greg's weight be x
\[\frac{180}{(x-20)}=\frac{4}{3}\]
4x-80=3*180
4x-80=540
4x=620
x=155

Greg's weight=155 pounds

Answer 2

thank u sooo much....:)
