Answer:
3/7 divided by 2/8 would be your simple equation to find the missing length:
3 8
__ x ___ = 24/14 *simplify* 1 10/14 *simplify more* 1 5/7
7 2
Explanation:
Make the divisor a reciprocal (just turning the fraction upside down) then turn the division sign into a multiplication sign and do multiplication across to get your final answer, 1 5/7 is your answer.
Whenever finding a missing side length always divide the area by the known given length.
