Answer:

You need 6oz (or 6.3366oz) of oil for the 5 gallon mixture.

Step-by-step explanation:

First, write down the essentials of this word problem.

The chainsaw uses 200 ounces gasoline (or gas) and 2 ounces oil.

The owner needs 5 gallons (640 ounces) of the mixture.

The chainsaw uses a 202 ounce mixture (200oz gasoline 2oz oil).

The mixture is 0.0099 repeating % oil and 0.9900 repeating % gasoline.

0.0099 (oil) x 640 (final mixture) = 6.3366oz repeating oil needed.

0.9900 (gas) x 640 (final mixture) = 633.6633 repeating gas needed.

This means you need 6.3366oz or 6oz (rounded) for the 5 gallon mixture.

CHECKING WORK:

6.3366 + 633.6633 = 639.99999997

OR ROUNDED:

6 + 634 = 640
