Question

Mary ran 3/4 mile, Lila ran 2/3 mile, and sue ran 3/8 mile.Who ran the farthest?Draw a diagram to solve.

Answer 1

Answer: Mary ran the farthest.

Step-by-step explanation:

To be able to see who ran the farthest you have to find the GCD (greatest common denominator) of all the denominators 4, 3, and 8, which turns out to be 24. If you multiply all the fractions, numerator and denominator, by what makes each individual denominator equal to 24, you can find the biggest one.

4 times 6 is 24, 3 times 8 is 24, and 8 times 3 is 24, so you multiply each fraction by those respective numbers to get 3/4 = 18,24, 2/3 = 16/24, and 3/8 = 9/24.

So, Mary ran the farthest.
