First convert inches to feet,
12 inches is to 1 foot
We have half of this, 6 inches = .5 feet
remember, 12 inches = 1 foot so 6 inches is to half .5 feet
To make the ratio table, if you double the smaller scale car then you do the same to the large scale car. If you triple the smaller scale car, then you triple the larger scale car.
for instance:
start with the original ratio scale:
6 inches : 16 feet
so lets cut in half
(half of 6 is 3, half of 16 is 8)
answer is
3 Inches : 8 Feet
now lets triple:
(6inch x 3 = 18inches: 16 ft x 3 = 48ft
18 inches : 48 feet
and so onremember, whatever you do on one side, you do on the other..

6.58-8.36x=3.98x-27.33
Collecting like terms
6.58+27.33=3.98x+8.36x
33.91=12.34x
33.91/12.34=12.34/12.34
x=2.75
