Typically, a pie is cut into 6 pieces but 8 is easier. A pie of firmer consistency, like custard, stands up better when cut into 8 pieces.
True
If a circle fraction can, a pie can yes
Four diameter cuts, if none of them are the same, will always cut a pie into 8 pieces.
It is not possible to cut a pie into seven pieces of equal area. Eight pieces and six pieces can both readily be done.
Because 4 pieces of something that was cut up in 9 pieces is more than 4 pieces of something that was cut up in 10 pieces. If you cut it up in 9 pieces instead of 10, then the pieces are bigger.
yes, that would create 8 pieces
No, seven tenths 7/10 is bigger than three tenths 3/10. If you had a pie cut into ten slices, would you rather have 7 pieces or 3? If you had 7 of those pieces, or 7/10 seven tenths, you'd have more of the pie than 3/10.
Yes. When you cut a pizza into 3 pieces, the pieces are bigger than they are when you cut it into 12 pieces.
Tanagrams
True. The first slice produces two pieces; the second slice intersects the first, bisecting each slice to produce four pieces; the third slice bisects two corner pieces to produce a total of 6 slices; and the fourth bisects two other corner pieces to produce eight slices
Assuming the pizzas were the same size to begin with. 2/10 = 0.2 2/100 = 0.02 0.2 is greater.
Cutting a diameter four time will get you eight pieces of pie, not seven. You cannot get 7 pieces by cutting diameters only; for that you need to cut radii.
