How do I do Fractions to percents?

Question

I have a worksheet where I have to draw lines from the Fractions to their right percents. but I don't know how to do that. Can somebody explain to me, I'll put down 3 examples and then if I see how to do those and somebody can tell me the way to do them, than that'd be great.

here are the examples this / equals the middle like 1/4 equals one over 4

7/50

3/25

4/5

it would be very helpful.

Answer 1

First rewrite the fractions as x/100 to make it simpler. For example, 7/50 = 14/100 (multiply top and bottom by 2). The percent is just the numerator. For example, 14/100 = 14%. So for those examples:

7/50 = 14/100 = 14%
3/25 = 12/100 (multiply by 4) = 12 %
4/5 = 80/100 (multiply by 20) = 80%

If you need to find out what to multiply by to get the denominator to be 100, just divide 100 by the denominator. For example, with 7/50, do 100/50. You get 2, so you know you have to multiply the top and bottom by 2.

Answer 2

Percents are always based out of 100, so when you get 80% on a test. you've gotten 80 out of a possible hundred. In that case 80 goes on top and 100 on bottom. The easiest way I learned percentages was to multiply or divide to get the denominator, or the digit under the line, to equal 100 and do the same action to the top number, or numerator. Try example 7/50. 50 x 2 = 100 so multiply 7 by 2 and that will give you 14 out of 100 or 14%. You can divide the denominator into 100 to get your number. 100 divided by 50 is 2. 2 times 7 is 14. For 3/25: 25 goes into 100 four times. so multiply 3 by 4 and you get 12 over 100 or 12 percent.

If you're allowed to use a calculator to solve, the answer will be you a decimal. If you divide 4/5 you'll see 0.8 on your calculator. To get the percent, move the decimal spaces two spaces to the right. 0.8 is then 80 for 80 percent.

Hope this helps.

Answer 3

You need to make the denominator 100.

For the first one, you multiply the numerator (7) and denominator (50) by 2. Then you have 14/100. This is the same as 14%. If you use a calculator and divide 14 by 100, you will see .14, which as a percentage would be 14% (you move the decimal point).

For 3/25, multiply the top and bottom by 4 to make the denominator 100. You end up with 12/100 or 12%.

For 4/5, multiply top and bottom by 20 so you have 80/100. This translates to 80%.

Hope this helps.

Answer 4

times by 100 4/5 *100 but you should memorise easy ones like that as just 80% another way of thinking is thata percent is a fraction over 100 what factor must the denominator be multiplied by to get 100, well that answer is 20 times by 20 on top and bottom(this equals 1) 4 X 20=80%

Answer 5

To convert these fractions to percents, I would convert each of the fractions to new fractions with a denominator of 100. Then it's easy.

In the examples you gave, you'd do it like this:

7/50 = 14/100
3/25 = 12/100
4/5 = 80/100

The numerator (# on the top) is now your percent! The first answer is 14%, the second is 12%, and the third 80%.

Answer 6

1/4 = one divided by four = .25 and to make it a percent multiply by 100 so .25 times 100 = 25%

7/50 = .14 = 14%

3/25 = .12 = 12%

4/5 = .8 = 80%

Answer 7

On these, just multiply the bottom number times whatever you need to get 100. For example, the first one you would multiply by two: 50 x 2 = 100. Then multiply the top number by the same thing. 7x2=14. So 14/100 would be read as fourteen hundredths and converts to 14%. So your next problem would be taking it times 4; 12%. Adn the last would be times 20, which would eventually give you 80%. =) I hope that helped you, and good luck with the rest of your worksheet! =D

Answer 8

Very Simple to do:
Just divide the numerator (top number of the fraction) by the denominator (bottom number of the fraction) then multiply by 100.
So to answer your first problem 7/10 you:
7÷10=0.7
0.7x100=70%

Second Problem:
3÷25=0.12
0.12x100=12%

Third Problem:
4÷5=0.8
0.8x100=80%

Answer 9

i dont know how to do it but ill use a calculator to do it on there
1/4 is 25%
7/50 is 14%
3/25 is 12%
4/5 is 80%
i think you divide the numbers into each other then multiply by 100

Answer 10

just divide the numerator by the denominator, and then u'll get a decimal for your answer. move the decimal point two places to the right and add the percent sign

like here for example...

7/50: divide 7 by 50 and u get 0.14. now move the decimal point over, add the percent sign, and u get 14%

3/25: divide 3 by 25 and u get 0.12. move the decimal, add %, and u get 12%

4/5: divide 4 by 5 and u get 0.8...move decimal over, and u get 80%

hopefully that would help =)
