Question

Read the problem and examine the diagram. Of all the students in the school band, 6 play the trumpet. They represent 10% of the total number of students in the band. How many students are in the band? Which choice is NOT a correct way to check your answer?

Answer 1

Since the 6 are 10% of the school band, multiply 6x10=60:)

Answer 2

10% - 6 students
20%- 12 students
30%- 18 students
40%- 24 students
50%- 30 students
60%- 36 students
70%- 42 students
80%- 48 students
90%- 54 students
100%- 60 students

ANSWER: 60 students are in the band

CHECK:
I know that 50% is 30 students so I can multiply 30 students by 2 because 50 percent is 1/2 and to make it a full 100% you need to multiply 50 by 2.

30 students x 2= 60 students

the final answer is reasonable and correct
