Question

How do you solve `\frac { x } { 12} = \frac { 12} { 7 2}`?

Answer 1

See a solution process below:

Explanation:

Multiply each side of the equation by `color(red)(12)` to solve for `x` while keeping the equation balanced:

`color(red)(12) xx x/12 = color(red)(12) xx 12/72`

`cancel(color(red)(12)) xx x/color(red)(cancel(color(black)(12))) = 144/72`

`x = 2`
