-4.9t^2 + 6.1t - 0.8 = 0
Subtract 3 from both sides
let's firstly convert the mixed fraction to improper fraction and then multiply.

Try the first option if that's an option
Answer:
7 1/17 shifts
Step-by-step explanation:
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
