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?

Respuesta :

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. 
The rule of three:

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

Solving:

[tex] \frac{16}{40} = \frac{1}{y} [/tex]
Cross multiplies
[tex]16*y = 40*1[/tex]
[tex]16y = 40[/tex]
[tex]y = \frac{40}{16}[/tex]
[tex]\boxed{y=2.5}[/tex]

Answer:
2.5 o
