Question

1. Avital counted 40 green cars and 20 silver cars in the parking lot. If the number of green cars stay the same, how many more silver cars would need to be added so the ratios of green to silver cars is 1 to 4?​

Answer 1

X represents the number that would be added to the silver cars.


x/40= 4
X=40x4
x=160

Subtract the given 20 from 160 because 160 is the total number
160-20=140
Therefore 140 would be added to 20 silver cars to get the ratio1:4
