A coin weighs 5/6 ounces. Ann picked up 3 of these coins. What is the total weight of the coins she picked up?
Write your answer in simplest form.

How I’d do it:
5/6 three times makes 15/6. Made into a mixed fraction is 2 3/6, which in its simplest form is 2 1/2.
When converted to ounces, assuming that 6/6 is one complete ounce, then you get 2.5 ounces.
The total weight she picked up is 2.5 ounces.

steps below

Step-by-step explanation:

1.   y=-3x + 4            (6,-2)

y' slope: 1/3   (perpendicular)

y' = mx + b

b = y' - mx = -2 - (1/3) x 6 = -4

equation: y' = 1/3 x - 4

2.  -2x -8y = 16             (4,5)

8y = -2x - 16          y = -1/4 x - 2

perpendicular line slope: 4

b = y - mx = 5 - 4 x 4 = - 11

equation: y = 4x - 11

3. x+y= 2             (8,5)

y = -x + 2     slope: -1

perpendicular slope: 1

b = y - mx = 5 - 1 x 8 = -3

equation: y = x -3
