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.

If you want to find the price of the confetti per ounce, you need to use an operation that makes sense.

If 1 lb. = 16 oz.

And she paid $12 for 1 lb, the operation you'd need to use is division.

If you divide the cost by the ounces, which is 12 and 16, you'd get 0.75.

Multiply 0.75 by 2 four times.

0.75 x 4 = 12

So, Yuki will pay $2 per ounce for the confetti.
