Question

julia saw 5 times as many cars as trucks in a parking lot. if she saw 30 cars and trucks altogether in the parking lot, how many were trucks?

30 / 6 = 5 there are five groups of.... the group.

for each group, there is only 1 truck, and there were 5 groups.
Therefore, in the parking lot, there are total of 5 trucks.
