3.2 Jane and Anna bought a pizza. Jane ate one third of the pizza and Anna ate one fifth of the pizza. How much of the pizza is left over?

To find out how much pizza is left over, we first need to calculate how much Jane and Anna ate together. Jane ate one third (1/3) of the pizza and Anna ate one fifth (1/5). To add these fractions, we need a common denominator, which is 15 in this case. Jane's portion: 1/3 = 5/15 Anna's portion: 1/5 = 3/15 Now, we can add their portions: 5/15 + 3/15 = 8/15 Now, to find out how much pizza is left, we subtract the portion they ate from the whole pizza (which is 1 whole, or 15/15): 15/15 - 8/15 = 7/15 So, there is 7/15 of the pizza left over.
