Question

at a school pep rally, the ratio of students who wore red to those who wore yellow is 7 to 3. There are 300 students at the pep rally, and each student wore either red or yellow. How many more students wore red?

Answer 1

300 total, divided by 10 is 30. 30 x each part of ratio gives:
30 x 7 = 210 - red
30 x 3 = 90 - yellow
210 - 90 = 120 more students

Answer 2

120 more students


I hope this helps and have a wonderful day filled with joy!!
