Answer:
They spent 7 1/4 hours on homework
Step-by-step explanation:
you can take out 2/4 from 3/4 and make it into 1/2 and 1/2 + 1/2 = 1
1 + 6 = 7
the only fraction left is 1/4 so,
Jonah and Jan spent a total of 7 1/4 hours on homework.
or
you can make 1/2 into 2/4 and add 3/4 and 2/4 together which gives you the same answer:
7 1/4 hours on homework
