Question

Mr. Sinofsky used 5/8 of a tank of gas on a trip to visit relatives for the weekend and another 1 half of a tank commuting to work the next week. He then took another weekend trip and used 1/4 tank of gas. How many tanks of gas did mr. Sinofsky use altogether?

Answer 1

Get all the fractions to have a common denominator. The common denominator is 8. 1/2 will turn into 4/8, and 1/4 will be 2/8. Add them all up and you will find he used 11/8 tanks of gas which can simplify into 1 and 3/8 tanks of gas

Answer 2

The total tanks of gas that Mr sinofsky used altogether is 1³/₈

• The tank of gas used over the weekend by Mr sinofsky is 5/8
• The tank of gas commute to work for next week is 1/2
• The tank of gas used for weekend trip is 1/4

Further Explanation

To get the total tanks of gas used by Mr sinofky, then we have to calculate the fraction of all the tanks of gas used by Mr sinofsky, this implies 5/8+1/2+1/4.

To get the correct answer, you have to look for particular smallest number that can divide all the denominators (8, 2 and 4), therefore the number that can divide the denominator is 8.  

8 is also refers to as the lowest common denominator or LCD.

Since we have 8 as the LCD, then we should divide the all denominators with the LCD and multiply the answers you get with the numerators.  

That is 5/8+1/2+1/4 which gives 5/8+4/8+2/8 = 11/8.  

The final answer is 1³/₈

We add all the numerators together to arrive at 11 while the LCD remains the same.

In case the denominators are large, you can find the LCD by multiplying the three denominators together and reduce it if needed.
