How to add fractions with unlike denominators?
Ainat [17]
Change the fractions so they have common denominators. For example. If adding 4/8 + 2/3, a common denominator of the two could be 24. Change both fractions to have a denominator of 24. To do this:

(4/8)×(3/3)= 12/24
(2/3)×(8/8)=16/24

Now that both fractions have denominators of 24, you can simply add the numerators to get your answer. in this case, it would be 28/24

This can't work because if there are 60 cars that means there are 240 car wheels and then 25 bikes means 50 bike wheels for a total of 290 wheels, if there was 1 more car then it would be 86 cars and motorcycles with 294 wheels or 2 more bikes would mean 87 cars and motorcycles with 294 wheels
