Question

Two batches of chocolate chip cookies call for 40 ounces of chocolate chips. If there are 16 ounces in a pound, how many pounds of chocolate chips are in the two batches?

Answer 1

The rule of three:

ounces _____ pound
16 ----------------- 1
40 ----------------- y

Solving:


`(16)/(40) = (1)/(y)`
Cross multiplies

`16*y = 40*1`

`16y = 40`

`y = (40)/(16)`

`\boxed{y=2.5}`

Answer:
2.5 of chocolate chips are in the two batches

Answer 2

2.5 pounds of chocolate chips.
You have to divide 40 by 16 to get the amount of pounds in two batches. 40/16 is 2.5.
