Question

Yuki bought a pound of confetti for $12. What is the price, in dollars, per ounce of confetti? There are 16 ounces in 1 pound.

Answer 1

For this case we can solve the problem by applying the following rule of three:
 16 ounces ----> 12 $
 1 ounces ------> x
 Clearing x we have:
 x = (1/16) * (12)
 x = 0.75 $ / ounce
 Answer:
 The price, in dollars, per ounce of confetti is:
 x = 0.75 $ / ounce
