If you do 17 - 15 the answer will be positive but do the reverse and u get a negitive same for division
For this kind of problems, first find the method to solve, then face the fractions.
If I jog 100 miles in a year, and I do 2 miles a day. How many days did I jog?
We know easily that it is 100 days/ 2 miles/day = 50 days.
So the number of days is total distance / how much a day, or
(6 1/2) divided by (1/6)
I’m pretty sure it’s c, sorry if i’m wrong
