Question #c4bdd

1 Answer

Answer:

Melissa ran #11 29/60# miles in all.

Explanation:

To solve this problem, first, you need to find a common denominator, also known as a least common multiple (LCM). The LCM of #3#, #4#, and #5# is #60#, so you know you need to change all of the fractions to a denominator of #60#.

  • #2/5# is equal to #24/60#
  • #3/4# is #45/60#
  • #1/3# is #20/60#

Add these up and you get #89/60#. Change this into a mixed number and you get #1 29/60#. Then you add the mixed numbers and get #6+2+2#, which is #10#.

#10 + 1 29/60 = 11/60#

so this is your final answer.
