if 60 2/3 litres of Gasoline are added to a tank that already contains 5 and a half (1/2 ) litres what is the total?

need to add the two together. To do so we add 60 and 2/3 to 5 and 1/2. But to add the fraction component we need the bottom of both to match, finding the lowest common denominator. Also to multiply the top by any multiple of change at the bottom.

ie.
Now the equation is 60 and 4/6 + 5 and 3/6 litres. WE can add them, 60+5 and 4/6 + 3/6 equal to 65 and 7/6 litres. The 7/6th component is also the same as 6/6 + 1/6. the 6/6 is a whole so we have 66 litres and 1/6 total. The 1/6 is 1000/ 6 to find out the value in millilitres. I'l leave that to you.

here is a calculator. Just plug the numbers and same sign in as you would a normal calculator for a straight forward answer..

the lowest common denominator, is the lowest number which is a multiple of both fractions bottoms. When we multiply the bottom on either or both we need to make the top also multiplied by the same amount. Means 3/4 and 4/3 we need 12 on the bootom of both, the 3/4 is multiplied by 3 on the bottom and the 4/3 multiplied by 4 on the bottom so we multiply the top of both respectively as given.
Don''t forget to give your answer in litres.

Good luck.

That is a very good answer Stu.

There are two methods to do this:
1. You can change each fraction to have a like denominator.

For example- 6 7/8= 6 21/24

7 2/3= 7 16/24
OR
You can change them into improper fractions.


Hope this helps? You can also use the scientific calculator, but maybe your teacher doesn't want you using them.

well GUEST, the op would still need in the case she can't use a calculator to work out the remainder left as litre and some method to calculate. That would have been nice to give op a hand with given your insight.
