Question

The purity of gold is measured in carats, or 24ths. 18 carats means 18/24 of pure gold. What is the percent of pure gold in an 18-carat ring?

Answer 1

the answer is 75%

Explanation:

let's break this up a bit.(don't mind the fact that i'm bad at explanations).

18 is a multiple of 6, and we know that 24÷6=4. Therefore, 6 would be 25% of 24. Because 18 is a multiple of 6, 6*3=18.

Replace 6 with 25%, and 25x3=75.

Therefore the answer is 75%. Sorry my explanation sucked but there you go!

Answer 2

75%

Explanation:

percent = part/whole × 100%

Here, the part is 18 carats, and the whole is 24 carats.

percent = 18/24 × 100%

percent = 0.75 × 100%

percent = 75%
