A bus holds 30 students comfortably. If 360 students out of the student body are going on a trip, what percent of the total body is this, if there are 900 students in the school?

Hmm isn't the "bus holds 30 students" irrelevant and is just to confuse you? If so then:

\(\displaystyle \L \; \frac{360}{900}\, \to\frac{36}{90}\, \to\,\frac{12}{30}\, \to\,\frac{6}{15}\, \to\,\frac{2}{5}\,= \,0.4\)

Whenever you you divide the numerator and then denominator and you get that number.........you alway move the decimal place 2 places to the right.

..................So:\(\displaystyle \L\;.4\,=\,40%\)
