Find the common denominator:
3 6 9
-- -- --
7 14 21
1 2 3 4 5 6 7 8
-- -- -- -- -- -- -- --- ---
3 6 9 12 15 18 21
Ok, so we know the common demonators are 9/21 and 8/21
Now we subtract 9/21 and 8/21 which is 1/21
So.. There is 1/21 pizza left!
Hope this helped :))
First, change the fractions to a common denominator, which is 21.
so 3/7 * 3/3 = 9/21
1/3 * 7/7 = 7/21
Add the two together
9/21 + 7/21 = 16/21
Then take 21/21 - 16/21 = 5/21
There is 5/21 of the pizza left.

Hello,
a(2)=-6
a(3)=-6*r
a(4)=-6*r²
a(5)=-6*r^3=162
a(5)/a(2)=r^3=162/(-6)=-27==>r=-3
a(1)=-6/(-3)=2
a(2)=2*(-3)
a(3)=2*(-3)²
a(4)=2*(-3)^3
a(5)=2*(-3)^4
a(n)=2*(-3)^(n-1)
