Question

There are 7 gallons of black paint available to motorola. If 5/9 gallons is used each run, How many runs can we paint?

Answer 1

There are 7 gallons of black paint available to motorola. If 5/9 gallons is used each run. To find the amount of runs you can paint, you have to divide the total by the amount for each run.

`7 / (5)/(9)`

When dividing fractions, you have to keep, change, and flip.

`Keep\ 7 \\ Change\ /\ to\ * \\ Flip (5)/(9) = (9)/(5)`

Your new equation is:

`7 * (9)/(5)`

Multiply:

`7 * (9)/(5) = (63)/(5) = 12 (3)/(5)`

You can paint
`12 (3)/(5)` or
`12.6` runs.
