Jordan bought 2 1/2 pounds of popcorn he used 1/2 of the bag to make popcorn for popcorn balls how many ounces of popcorn does he have left

Question

I need help please help

Answer 1

(2.5 pounds)(16 oz/pound) = 40 oz total 

 

(1/2)(40) = 20 ounces

 

He used 20 ounces and has 20 ounces left

Answer 2

2 1/2 = 5/2

 

(5/2)(1/2) = 5/4 = 1 1/4

 

Or, half of 2 is 1 and half of 1/2 is 1/4. 1 + 1/4 = 1 1/4
