At a school, 40% of the sixth-grade students said that hip-hop is their favorite kind of music. If 100 sixth-grade students prefer hip hop music, how many sixth-grade students are at the school? Explain or show your reasoning using a double number line.

250 students

Step-by-step explanation:

Let the number of sixth grade students be represented by = x

We were told that:

At a school, 40% of the sixth-grade students said that hip-hop is their favorite kind of music. 100 sixth-grade students prefer hip hop music.

Hence:

40% of x = 100

40/100 × x = 100

40x/100 = 100

Cross Multiply

40x = 100 × 100

x = 10000/40

x = 250

The number is sixth-grade students is 250 students
