Question

How do you simplify `\frac { s } { 4} = 4.2`?

Answer 1

See the entire simplification process below:

Explanation:

Multiply each side of the equation by `color(red)(4)` to solve for `s` while keeping the equation balanced:

`color(red)(4) xx s/4 = color(red)(4) xx 4.2`

`cancel(color(red)(4)) xx s/color(red)(cancel(color(black)(4))) = 16.8`

`s = 16.8`
