Mark is training for a mini triathlon he rode his bike 3/4 of a mile, ran 5/6 of a mile , and swam 10/12 miles each day for 7 days. what combined distance did mark exercise during the week?

Add the distances together then multiply by 7 days.

STEP 1:
=3/4 + 5/6 + 10/12
need a common denominator of 12
=9/12 + 10/12 + 10/12
=29/12 miles in one day (or 2 5/12)

STEP 2:
=29/12 * 7 days
=(29*7)/12
=203/12 miles
=16 11/12 miles in 7 days (or 16.9166)

ANSWER: 16 11/12 miles in 7 days

Hope this helps! :)
