Mrsjones has 1 4/8 pizza left after giving some to Greg she had 7/8 left how much did Greg take

5/8

Step-by-step explanation:

well we 1 14/8 so lets turn that to a whole number which is 12/8 (you multiply the denominator by 1 and add the 4)

12/8 - 7/8 = 5/8 (since both denominators are the same numbers you can simply subtract the numerator)
