Ratio and Proportion
The ratio shows how many times one number contains another. It is a comparison between two quantities. Then, two equal ratios form a proportion. It refers to the statement of equality between two ratios. You can easily determine whether the ratios are proportional if the product of their means is equal to the product of their extremes. Remember that the means are the inner terms while the extremes are the outer terms.
Let us now make a proportion by pairing the given ratios.
1:2 = 4:8
means: 2 × 4 = 8
extremes: 1 × 8 = 8
3:9 = 9:27
means: 9 × 9 = 81
extremes: 3 × 27 = 81
12:20 = 9:15
means: 20 × 9 = 180
extremes: 12 × 15 = 180
8:10 = 40:50
means: 10 × 40 = 400
extremes: 8 × 50 = 400
5:7 = 25:35
means: 7 × 25 = 175
extremes: 5 × 35 = 175
33:27 = 11:9
means: 27 × 11 = 297
extremes: 33 × 9 = 297
7:2 = 14:4
means: 2 × 14 = 28
extremes: 7 × 4 = 28
36:30 = 30:25
means: 30 × 30 = 900
extremes: 36 × 25 = 900
17:10 = 34:20
means: 10 × 34 = 340
extremes: 17 × 20 = 340
2:7 = 6:21
means: 7 × 6 = 42
extremes: 2 × 21 = 42
