Question

Solve for x in the proportion 3 over 8 equals x over 12

Answer 1

We have:
\[\frac{ 3 }{ 8 } = \frac{ x }{ 12 }\]To solve this we want to start by cross multiplying. So we get:
\[3 \times 12 = 8 \times x\]Now to solve for x we just divide both sides by 8:
\[x=3 \times 12 / 8 = 36/8=18/4=9/2\]

Answer 2

so x = 36? what next

Answer 3

No, x is equal to 9/2. And you're done.
