Answer:
4/5 * 3/2
Step-by-step explanation:
fraction division = multiplying the first fractions by the reciprocal of the second fractions (the tops are bottoms are flipped).
Sam sold half as many as Odel.
That means Odel sold twice as many as Sam.
Let x = number of pizzas sold by Sam.
Then Odel sold 2x.
Altogether they sold 126
x + 2x = 126
3x = 126
x = 42
Since x is the number of pizzas sold by Sam, that is our answer.
Answer: Sam sold 42 pizzas.
