Answer:
247.4
Step-by-step explanation:
- you can either use pi*diameter or 2pi*radius
- ![\pi (78.75) = 247.4](https://tex.z-dn.net/?f=%5Cpi%20%2878.75%29%20%3D%20247.4)
Just do 27/39 to find how much 27 is of 39, and then subtract that from 100 to get the percentage of discount.
27/39 is about 0.69
So the rate of discount is about 0.31
Hope this helps!

-1 1/5 + - 3/5

On the number line start at - 1 1/5 and go to the left 3/5( since the sign is negative) you will end up at - 1 4/5
