Question

Question 1: Harry has 4 ⅞ of a pizza and Mary has 1 ⅞ of a pizza. What is the estimated total of pizza they have together? ________

question 2: Sally has 5 ⅜ of a candy bar. She gives Omar 2 1/4 of the candy bar. Using benchmark fractions, determine how much of the candy bar Sally has left. Remember to estimate. _________

PLEASE HELP ASAP!!!

Answer 1

`6(3)/(4)` and
`3(1)/(8)`

Explanation:

I don't know what benchmark fractions are but here's what I did

`4(7)/(8) + 1 (7)/(8) = 5 (14)/(8) = 6 (6)/(8) or 6(3)/(4)\\5(3)/(8) - 2(1)/(4) = 5(3)/(8) - 2(2)/(8) = 3(1)/(8)`

The first question is straight forwards since the fractions have the same denominator, so its simply adding and simplification.

The second questions needs you to find a common denominator (8) and swap the fraction to that of 8 before subtracting
