Question

Gary’s family has 20 slices of pizza for dinner. His sister took 1/10 of the slices, his brother ate 25% of the slices, and his parents ate 2/5 of the pieces. How many pieces were left for Gary to eat

Answer 1

Okay so
1/10 of 20 is 2.
25% of 20 is 5.
2/5 of 20 is 8.
Add these together: 15
20-15=5.
This means there are 5 slices left for Gary.

Hope this is helpful!!
