1. Direct Proportion As one value increases, so does the other. 2. Indirect Proportion As one value increases, the other decreases. 3. Partitive Proportion A proportion describing the total amount being distributed into two or more unequal parts. Miwa D. Oguro

To solve a proportion, you cross multiply. For example, if this was the proportion: 2/4 = 3/x, you would multiply 2 with x and 4 with 3. The products will be used in your next equation. In this case, your next equation is 2x = 12. Now you want to isolate x, so divide by two for both sides. Your answer will be x = 6.

Is it 15 over 40?

3/7=x/63 189=7x 27=x

3/8=x/56 168=8x 21=x

3/7=x/56 168=7x 24=x

That would depend on the specific problem. The "rule of three" (i.e., solving proportions) can help for many standard problems; i.e., you consider a proportion, where the percentage has a denominator of 100. Here are some examples:1) What's 17% of 2000? The proportion to solve is: 17/100 = x/2000 2) 500 is what percentage of 2000? The proportion to solve is: x/100 = 500/2000 3) 500 is 10% of what number? The proportion to solve is: 500/x = 10/100

3/9 = x/81 x = 27 So: 3/9 = 27/81

32 - 121 - 64 = 36x => -153 = 36x so that x = -4.25

Father will give 1070.00 to his 3 children in the ratio 5:3:2. How much will each child get? Solution: 5n+3n+2n=10n 1070/10=107 N=107 5(107)=535 3(107)=321 2(107)=214 Final answer=535:321:214

Call the unknown distance travelled in four hours d. The proportion is 225/3 = d/4, or d = (4)(225)/3 = 300 miles.
