Question

How do you solve `\frac { b } { 100} = \frac { 55} { 89}`?

Answer 1

See a solution process below:

Explanation:

Multiply each side of the equation by `color(red)(100)` to solve for `b` while keeping the equation balanced:

`color(red)(100) xx b/100 = color(red)(100) xx 55/89`

`cancel(color(red)(100)) xx b/color(red)(cancel(color(black)(100))) = 5500/89`

`b = 5500/89`

Or

`b = 61.798` rounded to the nearest thousandth.
