Divide. 5/7 ÷ 3<br><br> Express the answer in simplest terms.
vlada-n [284]

Divide:


\frac{5}{7} : 3 = \frac{5}{7} x \frac{1}{3} = \frac{5x1}{7x3} = \frac{5}{21}



To divide one fraction by another, invert (turn upside-down) the second fraction, then multiply.


Result:

5/7 ÷ 3 = \frac{5}{21}

≅ 0.2380952


Hope this helped
