a survey conducted in a school showed that 65% of the students walked to school. The remaining students took buses to school. The ratio of students who took school buses to those who took public buses was 4:3. There were 360 more students who walked than took buses. How many students took public buses to school. Explain what and why you did what you did.

Answers

This means 35% used buses. 3+4=7, so 20% took school buses while 15% took public buses. 65%-35%=30% who mean the difference, so 30% is 360. You ask what is 15% -- that's half of that difference, or 180.
