Answer:
7 buses
Explanation:
when doing a problem like this you have to divide the larger group of people by the smaller group
78 divided by 12 = 6.5
if u answered this multiplication problem correctly you would get 6.5 but u cannot put .5 people on a bus lol. so therefore u are not done yet... so u need to round up
here's a poem to help with ur rounding...
Find a place look next door
4 or less let it rest
5 or more raise the score!!!
so in conclusion your answer would be 7!
