Question

A recipe that serves 8 calls for 1 1/2
pounds of ground beef. How many
pounds are needed to serve 12?

Answer 1

Hmm well we can set up a proportion

\[\frac{ 8 }{ 1.5 } = \frac{ 12 }{ x }\]

Cross multiply and solve for 'x'

Answer 2

I tried that and for some reason it didn't come out right..

Answer 3

So lets see....

8 times x = 8x

12 times 1.5 = 18

so we have

\[8x = 18\]

Now we divide both sides by 8 to solve for 'x' and we get

\[x = 2.25\]
