Answer:
4 busses are needed. Well 135 students going on a field trip and each bus holds 40 students. There can’t be “half” a bus but instead you can have a bus thats not all the way filled. Plus youc an’t duplicate or divide the a light of children so 4 busses.
Explanation:
40x ≥ 135
Solve that and the answer has to be a whole number greater then the proposed decimal.
135/40= 3.375
3.375 and it can’t be rounded down and only up to the nearest whole digit so round it to 4.
4 busses.
