Question

fifty-six out of 128 students went on a trip during vacation. what percent of students went on trips?

Answer 1

Set up a proportion, where x = the percentage:


`(56)/(128)=(x)/(100)`

Then, cross multiply and solve to isolate the x:


`(56)/(128)=(x)/(100)\\128x=5600\\x=5600/128\\x=43.75`

So, 43.75% of the students went on trips.
