Question

How do you solve `\frac { 18} { 54} = \frac { x} { 3}`?

Answer 1

See a solution process below:

Explanation:

Multiply each side of the equation by `color(red)(3)` to solve for `x` while keeping the equation balanced:

`color(red)(3) xx 18/54 = color(red)(3) xx x/3`

`54/54 = cancel(color(red)(3)) xx x/color(red)(cancel(color(black)(3)))`

`1 = x`

`x = 1`
