*3. Analyze Martin completed 60% of his math assignment during class.
If his math assignment consists of 30 problems, how many problems does he have left to do?
Answer provided by our tutors
Martin completed 60% of 30 problems
the number of problems left to do is: 30 - (60% of 30) that is
30 - (60/100)*30 = 30(1 - 60/100) = 30 (1 - 0.6) = 30*0.4 = 12 problems
Martin has 12 problems left to do.
