To multiply exponents, you add them. To divide exponents, you subtract them. The answer would be 5 to the power of -3. However, we need to change that. 5 to the power of -3 is equal to 1 divided by 5 to the power of 3. 1 divided by 5 to the power of 3 is correct.
1 2/3 = 5/3
2 3/4 = 11/4
5/3 ÷ 11/4 = 5/3 × 4/11
= 20/33
