What are the 3 different kinds of proportion?
*direct proportion - As one values increases, so does the other. *indirect proportion - As one values increases, the other decreases. *partitive proportion - involves identifying parts of a whole based on a given ratio of these parts.
Kinds of proportion?
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
Solve the proportion 3 over 8 equals x over 40?
Is it 15 over 40?
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.
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
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
Solve the proportion 3 over 9 equals x over 81?
3/9 = x/81 x = 27 So: 3/9 = 27/81
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 this proportion. 3/4 = 36/x x = what does x =?
32 - 121 - 64 = 36x => -153 = 36x so that x = -4.25
Examples of partitive proportions?
1. Divide 1035 in the ratio of 2:3:4.2. A father wants to leave $4675 to his four children in the ratio of 1:3:3:4. How much will each of the four children receive?3. John plans to donate his collection of 3042 books to three libraries in the ratio of 1:3:5. How many books will each library get?To get the answer, divide the number representing the total, by the sum of the terms in the ratio then, multiply the quotient by each of the term in the ratio.1. 1035 = number representing the total2, 3 and 4 = terms in the ratio9 = sum of the terms in the ratio1035 / 9 = 115then, multiply 115 by each of the term in the ratio115 X 2 = 230115 X 3 = 345115 X 4 = 460Final Answer = 230, 345 and 460To check, add them all230 + 345 + 460 = 10352. $4675 = total amount father wants to leave to the children1, 3, 3 and 4 = terms in the ratio11 = sum of the terms in the ratio$4675 / 11 = $425so, we need to multiply this by each of the term in the ratio$425 x 1 = $425$425 x 3 = $ 1275$425 x 3 = $ 1275$425 x 4 = $ 1700Final Answer = $425, $1275, $1275 and $1700To check,$425 + $ 1275 + $ 1275 + $ 1700 = $ 46753. 3042 = total number of books1, 3 and 5 = terms in the ratio9 = sum of the terms in the ratio3042 / 9 = 338when multiplied by each term in the ratio, we get338 x 1 = 338338 x 3 = 1014338 x 5 = 1690Final Answer = 338, 1014 and 1690to check338 + 1014 + 1690 = 3042
