Mother saved 7/8 of a pie for dinner. Her son came home from school and ate the pie. How much pie is now left for dinner
None. The son ate the pie that had been saved for dinner.
None because the son ate it all
To calculate the amount of pie left for dinner, we need to subtract the amount eaten by the son from the amount saved by the mother.
The mother saved 7/8 of the pie, which means she kept (7/8) of the whole pie.
Now, if her son ate the entire pie, we need to subtract that from the amount saved.
Subtracting (7/8) from (1/1), we get:
(1/1) - (7/8) = (8/8) - (7/8) = 1/8
So, the son ate 1/8 of the pie, leaving 1/8 of the pie for dinner.
