For my kid
I didn't eat a slice of pie, I ate a pie - so no slices are left.
Peter = n slices Ben = 3+n slices George = l/2(3+n) = 1.5+ 1/2n n + 3 + n + 1.5+ 1/2n = 12 2.5n = 7.5 So n = 7.5/2.5 = 3 Peter ate 3 slices, Ben ate 6 slices and George ate 3 slices = 12
he ate two slices.
Well, it mostly depends on how many slices there are in each pizza.
This depends on whether you ate 1 slice, which would leave 3; 2 slices, which would leave 2, or 3 slices, leaving only 1.
4 pizzas were each cut into 8 slices.Therefore there were 4*8 = 32 slices in all. 27 were eaten, which leaves 32 - 27 = 5 slices. These 5 slices made up 5/8 of one pizza.
She ate 3/4.
One sixth or 1/6...assuming the pizza was cut into 6 slices. If not, then the fraction left would be: (total # of slices cut - 5)/total # of slices cut
7/10 is larger than 3/10. If you had a pie cut into 10 pieces, (which is all the 'tenths' part means, a whole cut into 10 equal parts), and you were really hungry and ate 7/10 (seven slices out of 10) you'd be more full than if you ate 3/10 of the slices, or 3 of the 10.
obviously assuming they are equal slices... 12-8=4, 4/12=1/3 1/3 = 33.3%
Two pieces. (see discussion)
1 and 1/5 cakes.
