12 is to x as 25 is to 100 x = 48
In a proportion, the means are the middle terms, and the extremes are the outer terms. Given the means are 6 and 18, and the extremes are 9 and 12, the proportion can be expressed as ( \frac{9}{12} = \frac{6}{18} ). Simplifying both sides, ( \frac{9}{12} ) reduces to ( \frac{3}{4} ), and ( \frac{6}{18} ) reduces to ( \frac{1}{3} ), indicating that these values do not form a valid proportion.
Well, honey, a proportion is formed when two ratios are equal. So, to find the missing number that forms a proportion with 12 and 7, you simply divide 12 by 7 to get approximately 1.714. There you go, math made sassy!
To do a proportion all you have to do is find the equivilent fraction. For example: 4/7=12/221
7:12
4/7 = 12/21
It depends on what that is. 312 : 624 is a ratio. 3 : 12 = 6 : 24 is a proportion.
12/20 = 3/5
