[quote=Anonymous][quote=Anonymous]You could alternatively solve the problem as follows, avoiding algebra. Start by eating 7 pepperoni slices. Since 15-7=8, we then have 8 slices left, and the number of cheese pizza slices is now the same as the number of (remaining) pepperoni pizza slices. Half of 8 is 4, so there are 4 slices of cheese pizza and 4 (remaining) slices of pepperoni. Thus at the beginning we have 4 cheese pizza slices and 7+4=11 slices of pepperoni pizza. (Another way is to buy 7 more cheese pizza slices making the number of slices the same between cheese and pepperoni, then proceed similarly). [/quote] wow, cool solutions, tks a lot! this is quite different but might just work for my kids![/quote]
