How To Solve A Proportion?
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?
Solve the proportion 3 over 7 equals x over 63?
3/7=x/63 189=7x 27=x
Solve the proportion 3 over 8 equals x over 56?
3/8=x/56 168=8x 21=x
Solve the proportion 3 over 7 equals x over 56?
3/7=x/56 168=7x 24=x
How can you solve problems involving percents?
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
Solve the proportion 3 over 9 equals x over 81?
3/9 = x/81 x = 27 So: 3/9 = 27/81
Solve this proportion. 3/4 = 36/x x = what does x =?
32 - 121 - 64 = 36x => -153 = 36x so that x = -4.25
Can you give me an example of partitive proportion?
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
Translate to a proportion and solve Jason has driven 225 miles in 3 hours If he averages the same speed after lunch how far can he expect to travel in 4 hours?
Call the unknown distance travelled in four hours d. The proportion is 225/3 = d/4, or d = (4)(225)/3 = 300 miles.
