Solve the proportion. 51.84 = 14.4 x x = 3.6 4.8 = x 14.4 10.8
Solve the proportion. 5x = 36 x = 7.2 5 = 3 12 x
Solve the proportion. 34x = 132.6 x = 3.9 x = 8.5 15.6 34
Identify the means and the extremes in the proportion. Means: 14.4 & x Extremes: 4.8 & 10.8 4.8 = x 14.4 10.8
x = 8.5 15.6 34 Identify the means and the extremes in the proportion. Means: 34 & x Extremes: 8.5 & 15.6
2 = x a 5b Identify the means and the extremes in the proportion. Means: a & x Extremes: 2 & 5b
2•5b = ax Which proportion is equivalent to 5b = a x 2 2 = x 5b a a = 2 5b x 2 = x a 5b 5b•2 = ax yes! 2a = 5bx no ax = 5b•2 yes!
3ez = 7x Which proportion is equivalent to 7 = e x 3z 3z = x 7 e e = 3z 7 x x = e 3z 7 3z•7 = ex nope 3ez = 7x yes ex = 3z•7 no
