Answer: 125 Red Cars
6:5 = 275; Write as equation by adding a variable to the ratio:
6x + 5x = 275; add
11x = 275; divide
x = 25; put 25 in for “5x,” which represents the ratio 5 for red cars
5(x) = 5(25) = 125
Check:
6(25) + 5(25) = 275; multiply
150 + 125 = 275; add
275 = 275; is true so answer is right.
3.92/2.8=1.4
Unless it’s reverse.
2.8/3.92=0.714285714285 and so on.
