Answer
A 7/10
Step-by-step explanation:
if you make it even, you double the 4/5 to make it a 8/10, if you every have a number that is like 4/6-2/18, you triple the 4 to make 12, and triple the 6 to make it 18. so you now have 12/18-2/18=10
So 8/10-1/10=7/10
Answer:
7 1/17 shifts
That would be 7 1/2 divided by 1 1/16
= 15/2 / 17/16
= 15/2 * 16/17
= 15 * 8 / 17
= 120/17
= 7 1/17 shifts
