Two employees are painting a boat. one uses ¾ gallon of paint each hour, one uses 1 ⅔ gallon of paint every 2 hours. how much paint will they use in 4 hours?

The answer is:

First employee: 3 gallons

Second employee: 3 1/3 gallons

Total:

From the statement we know:

First employee uses 3/4 gallon each our, for 4 hours the will use:

Second employee uses 1 2/3 (5/3) gallon every 2 hours, meaning 5/6 gallon each hour.

Remember, to sum (algebraic sum) fractions we should follow the next steps:

First: Multiply both fractions denominators by each other in order to get the denominator of the new fraction.

Second: Multiply the numerator of the first fraction by the denominator of the second fraction.

Third: Multiply the denominator of the first fraction by the denominator of the second fraction.

Fourth: Sum (algebraic sum) each result and divide it into the number obtained from the first step (denominator of the new fraction).

Example:
