To determine which set of ratios forms a proportion, we need to check if the two fractions are equal.
Let's calculate the proportions for each set:
1:8 and 2:18
1/8 = 0.125
2/18 = 0.111
9:10 and 45:40
9/10 = 0.9
45/40 = 1.125
1:16 and 3:18
1/16 = 0.0625
3/18 = 0.1667
5:10 and 20:40
5/10 = 0.5
20/40 = 0.5
Based on the calculations, the set of ratios that form a proportion is 5:10 and 20:40, as both fractions are equal to 0.5.
