Answer 1

10 5/24 pizzas

Explanation:

Total pizza = sum of pizzas

= 2⅝ + 4⅓ + 3¼

= (2 + 4 + 3) + (⅝ + ⅓ + ¼)

= 9 + [5(3) + 1(8) + 1(6)]/24

(LCM of 8,3 and 4 is 24)

= 9 + (29/24)

= 9 + 1 5/24

= 10 5/24

Answer 2

10 5/24 pizzas

Explanation:

2 5/8 + 4 1/3 + 3 1/4

The common denominator is 24

2 5/8 = 2 5/8*3/3 = 2 15/24

4 1/3 *8/8 = 4 8/24

3 1/4 * 6/6 = 3 6 /24

2 15/24 + 4 8/24 + 3 6/24

9 29/24

9 + 24/24 + 5/24

9 + 1 +5/24

10 5/24
