Question

Cyndi bought an extra large pizza, cut into 12 pieces, for today's meeting of the Mystery club. She ate 1/6 of the yesterday afternoon. Her brother ate 1/5 of what was left last night. Cyndi knows that she needs 8 pieces of pizza for the club meeting. Help cyndi figure out if she has enough pizza left for the meeting. PLEASE HELP -and show your WORK OR EXPLAIN

Answer 1

There are 12 slices of pizza, so each slice is 1/12 of the pizza. If she ate 1/6 of the pizza, or 2/12, then she ate two slices.

There are 10 slices left. Now each slice is 1/10 of the pizza, because there is less pizza, and the slices are the same size.

Her brother then ate 1/5, or, 2/10 of the pizza, leaving 8 slices.
