1/4 and 1/3 therefore she kept 5/12 for herself because u need to fine the LCD which is 12 then add them together and then subtract that by 12/12 ( which is all the nuts) to find how many you have left over
1/5( 5/2 x 4/7 -11/7) + 3/28
Multiply the terms (5/2 x 4/7) in bracket then subtract it from 11/14. Result will be 10/7.
Then multiply 1/5 with 10/7. The result will be 2/7.
2/7 + 3/28 = 11/28
T
Well r equals what ever number same for the c then what numbers you get from those 2 add to the p
If the radius is 7 and 3/4, then the answer is 48.6947
c=2pie•r
plug in 7 and 3/4 for r and get 48.6947
