Question

Solve the following proportion:

Answer 1

\[\frac{ x }{ 4 }=\frac{ 7 }{ 14 }\]

Answer 2

@hartnn , Do I just cross multiply?

Answer 3

@campbell_st @hero

Answer 4

Multiply both sides by 4, then simplify the right side.

Answer 5

\[\frac{ 4x }{ 16 }=\frac{ 1 }{ 2 }\]

Answer 6

You multiplied by 4/4

Just multiply by 4 on both sides and simplify.

Answer 7

Actually, reducing the right side was a good start, but you should have ended up with

\[\frac{x}{4} = \frac{1}{2}\]

Now you still have to multiply both sides by 4 to isolate x.

Answer 8

I'm so lost...

Answer 9

\[\frac{x}{a} = \frac{b}{c}\]
Multiply both sides by a:
\[a \frac{x}{a} = a \frac{b}{c}\]
The a's on the left side cancel:
\[x = a \frac{b}{c}\]

Answer 10

\[x=\frac{ 1 }{ 2 }(4)\]

Answer 11

Yep. Which simplifies to what?

Answer 12

2?

Answer 13

There you go :)
