what fraction of a pizza remains if Joe ate 4/5 of 1/2 a pizza
(4/5) * (1/2) = 4/10
(10/10) - (4/10) = ?
To find out what fraction of the pizza remains after Joe ate, we need to subtract the fraction that Joe has eaten from the original fraction of the pizza.
First, let's calculate what fraction of the pizza Joe has eaten. Joe ate 4/5 of 1/2 a pizza, so we can multiply these fractions together:
(4/5) * (1/2) = 4/10 = 2/5
So, Joe has eaten 2/5 of the pizza.
To determine what fraction of the pizza remains, we subtract 2/5 from the whole pizza, which is represented by 1:
1 - 2/5 = 5/5 - 2/5 = 3/5
Therefore, 3/5 of the pizza remains.
