solving proportions is simply a matter of stating the ratios as fractions, setting the two fractions equal to each other, cross-multiplying, and solving the resulting equation. You'll probably start out by just solving proportions, like this:
Find the unknown value in the proportion: 2 : x = 3 : 9.2 : x = 3 : 9First, I convert the colon-based odds-notation ratios to fractional form:.Then I solve the proportion:9(2) = x(3)
18 = 3x
6 = xFind the unknown value in the proportion: (2x + 1) : 2 = (x + 2) : 5(2x + 1) : 2 = (x + 2) : 5 ADVERTISEMENT First, I convert the colon-based odds-notation ratios to fractional form:Then I solve the proportion:
5(2x + 1) = 2(x + 2)
10x + 5 = 2x + 4
8x = –1
x = –1/8
