The ratio of 3 to 4 can be written in all the following ways except 4/3 3/4 3: 4 three-fourths

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6

6 cars because if you have 8 and subtract 2 youll have 6 left over
