In a parking lot, 3 out of 8 vehicles were trucks. if there were 128 vehicles, complete the ratio table to find the number of trucks:
table:
# of trucks | 3 | __
# of vehicles | 8 | 128
explain and simplify

This equals 3/8=x/128; because to cross multiply you put the smallest as the numerator or as the denominator as lose as they are across from their corresponding parts so 3/8=x/128 is the same as 8/3=128/x

to solve: cross multiply (by multiplying numbers diagonal from them); then solve as simple equation

3/8=x/128 goes to...
8x=(3*128)
8x=384 then solve by dividing both sides by 8
x=48 so 48 of the vehicles are trucks

Its d so thats how it would would back from 1.0 form three four two
