6 0

Length of rope bought by Sean = 68 3/4 inches
   = 275/4 inches
Then
The number of 15 inch rope that can be made by Sean = (275/4)/15
   = 275/(4 * 15)
   = 275/60
   = 4.58
So we can see from the above deduction that Sean can make 4 complete 15 inches ropes and there will be 0.58 inches of rope excess. <span>I hope the procedure and the method of solving is absolutely clear to you. This is the easiest way to get to the solution for such problems.</span>

I first divided 3/4 tk her 0.75
I then got 68.75 as the inches of rope.

If you then divide 68.75/15
you get 4.58333.....

Sean can make 4.58 - 15inch ropes

The notation just means

(f/g)(-4) = f(-4) / g(-4)

If f(x) = x² + 2 and g(x) = 1 - 3x, then

f(-4) = (-4)² + 2 = 16 + 2 = 18

g(-4) = 1 - 3 (-4) = 1 + 12 = 13

and so

(f/g)(-4) = 18/13
