24/30 = 12/15 = 4/5
this is the simplified form
Answer:
c 4 cal per minute
Step-by-step explanation:
because they burn 40 cal per 10 min and 40÷10 is 4 so 4 cal per 1 min
12/12 would be the fraction of all students...now subtract all of the fractions that represent students not in the volunteer programs...
12/12-2/12-4/12-1/12
(12-2-4-1)/12
5/12
So 5/12 of the student participate in volunteer programs.
