Answer:
0.008
Step-by-step explanation:
If you need to pay a deposit of $78 out of $359, you should only need to pay $281 afterwards, right?
First you have to make them to a common denominator.
5/6 7/12 7/10
50/60 35/60 42/60
from these the greatest value is 35/60 because 35 parts of 60 is bigger than the rest.
so the answer is 7/12
