(i need understanding percentages. explain how you got the answer) there are 160 students at school. yesterday 15% of the students were absent. how many students were present at school?

100%-15%=85%

160=100%

85%=?

85×100÷160

85%=136 pupils

reason

160 pupils is 100% when full and when 15% are absent meaning 85% are present. So if 160=100% what about 85%

Answer 136 pupils

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
