Determine the quotient

nexus9112 [7]

Answer:

option 2: $\large \frac{10}{12}$

Step-by-step explanation:

when dividing fractions, you can actually multiply them together by the reciprocal of the second one. (reciprocal is just flipping the fraction)

so, $\frac{2}{3}$ ÷ $\frac{4}{5}$

becomes $\frac{2}{3} * \frac{5}{4}$

to multiply fractions together, just multiply the top and bottom.

2 * 5 = 10

3 * 4 = 12

so the answer would be $\frac{10}{12}$
