WILL MARK BRAINLYIEST
Eddi Din [679]
Hello, and thank you for posting your question here on brainly.

When you're dividing two fractions, there's a simple rule to follow.

You flip the second fraction, (aka reciprocal) and then multiply.

2/3 ÷ 1/4 = 2/3 * 4/1

You multiply across from the top and bottom.

2/3 * 4/1 = 8/3

8/3 = 2 2/3

Your final answer is C.

Hope this helps! ☺♥
