Part A:
To find out how much leftover pizza Brad had, we need to add up the fractions of each type of pizza:
1/2 cheese pizza + 3/4 sausage pizza + 2/6 pepperoni pizza
We can simplify the fractions by finding a common denominator:
1/2 = 3/6
3/4 = 4.5/6
2/6 = 2/6
Now, we can add the fractions:
3/6 + 4.5/6 + 2/6 = 9.5/6
This means Brad had 9.5/6 of a pizza leftover.
Part B:
Steve had 2/3 of a pizza. To compare this to Brad's leftover pizza, we need to convert Brad's leftover pizza to a fraction with the same denominator as 2/3:
9.5/6 = 9/6 + 0.5/6 = 3/2 + 1/12 = 19/12
Now we can compare:
19/12 - 2/3 = 38/12 - 8/12 = 30/12 = 2.5
This means Brad has 2.5 more pizzas than Steve.
