Answer:
Explanation:
Total number of slices in the pizza = 16
Total number ate by John,
J = 7/12 * 16 = 28/3 = 9.3
Total number ate by Harold,
H = 4/23 * 16 = 2.783
Total number left over
L = 1/23 * 16 = 0.696
Total number ate by Betty
B = ?
All we have to do to get the total number eaten by Betty is to sum up that eaten by Harold and John, including the left over, then subtract it from the total pizza slices.
Betty = Total - (Harold + John + Left Over)
Betty = 16 - (9.3 + 2.783 + 0.696)
Betty = 16 - 12.779
Betty = 3.221
Therefore, Betty ate 3.221 of the total pizza as a whole
