Harriet has 3/4 tank of gas left in her car. if she needs 1/4 tank to go to her friends house and another 1/4 tank to get back home, does she have enough gas? explain why

Verified Answer :

Yes she does have enough. Here is why:
If you add 1/4 and 1/4, you get 2/8 which is also 1/2.
3/4 is bigger than one half. If you subtract 1/2 from 3/4, you get 1/4.
So she would have 1/4 left.
Absolutely enough to get to her friends house and back. :)

It would not be 2/8 it would be 1/2. When you add fractions together you don't add the denominator just the numerator and then simplify
