In a high school, 7% of the students play the piano this is 21 students choose the expression that complete each step involved in setting up and solving the proportion that represents the situation
[tex] \frac{7}{100} = \frac{21}{x} \\ x = \frac{21 \times 100}{7} = \frac{2100}{7} = 300[/tex] there are 300 students in the high school. hope this helps
