Question

Will give medal!

If you ate 1/4 of a pizza and there is 4 whole pieces left how many pieces of pizza were in the original pizza?

Answer 1

kind of tricky isn't it?

Answer 2

I'm think it is 5 whole pieces.

Answer 3

you ate \(\frac{1}{4}\) of the pizza, that leaves \(\frac{3}{4}\) of it left

Answer 4

i think the problem is there were not a whole number of slices in the pizza

Answer 5

OK.

Answer 6

either that or i am interpreting the problem wrong
when it says "there are 4 whole slices left" i take it to mean there are 4 whole slices, and not partial slices

Answer 7

OK so the whole pizza had 4 pieces?

Answer 8

three quarters of the pizza is 4 slices, so each piece is \(\frac{3}{4}\div 4=\frac{3}{16}\) of he whole pie

Answer 9

2/16 is the answer?

Answer 10

therefore there are \(\frac{16}{3}=5\tfrac{1}{3}\) pieces to begin with, which doesn't really make sense

Answer 11

yeah.

Answer 12

hmm maybe i am messing up
give me a second

Answer 13

ok lets do it this way: call the number of slices in the whole pizza \(x\)
then we have \(\frac{3}{4}\) of the pizza left, and we know
\[\frac{3}{4}x=4\] this also gives
\[x=\frac{16}{3}\]

Answer 14

ok fine, it had five and a third slices
