Question

How do you solve `r/60=40/50`?

Answer 1

See the entire solution process below:

Explanation:

Multiply each side of the equation/ratio by `color(red)(60)` to solve for `r` while keeping the equation balanced:

`color(red)(60) xx r/60 = color(red)(60) xx 40/50`

`cancel(color(red)(60)) xx r/color(red)(cancel(color(black)(60))) = 2400/50`

`r = 48`
