Question

4 points The fifth grade students are going on a field trip. All 219 students will ride buses. Each bus has 30 seats that will be filled by students before the next bus in line is used. What fraction of the student seats on the last bus will be filled? * 30/219 O 9/30 O 21/30 O 219/240

Answer 1

We can start calculating this dividing the total number of students by the bus capacity:

`(N)/(S)=\frac{219\text{ students}}{30\text{ students/bus}}=7.3\text{ buses}`

We can conclude that there will be 7 full buses, and the last bus will have 0.3 of its capacity filled.

We can translate it into a fraction as:

`0.3\cdot(30)/(30)=(0.3\cdot30)/(30)=(9)/(30)`

The proportion 0.3 can be translated into a fraction that is 9/30.

We can also calculate the number of additional seats by calculating the number of students that go in the first 7 buses: 7*30=210 students. Then 219-210=9 students go in the last bus, so 9/30 of the seats are occupied.

Answer: 9/30
