Answer:
8 1/8
Step-by-step explanation:
1st I'm going to turn these into improper fractions with a golf swing (multiply the bottom, add the top, keep denominator the same)
3 times 4 + 3 = 15, so we get 15 over 4
4 times 8 + 3 = 35, so we get 35 over 8
Next I am going to give them a common denominator. (Their least common multiple is 8)
one denominator is already 8, so we need to fix the other one by multiplying it by two (multiply both sides)
15/4 times 2/2 = 30/8
Now we add the two fractions (DO NOT ADD DENOMINATORS)
30/8 + 35/8 = 65/8
Finally to make it a mixed number, ask self, how many times does 8 go into 65? 8 times. That's the whole number. what's left over? 1. That is the numerator. The denominator stays the same.
10 minutes : 8 problems
x minutes : 60 problems
10 * 60/8 = 150/2 = 75 minutes for 60 problems
