Top Answer

Lets say the percent is 20%

You know this is 20 over 100= 20/100

20/100= 10/50

10/50=1/5

to check you perform the operation

1 decided by 5 is 0.20 and 20%=0.20

0To change a fraction into percent: - Perform the division indicated by the fraction. - Multiply the quotient by 100.

Percent means to divide by 100. so if given 25%, the decimal equivalent is 25/100 which is 0.25. Likewise if given 12.4%, the decimal equivalent is 0.124. (Notice how the decimal moves two places to the left.)

Percent literally means divide by one hundred. So divide the number by 100 and then bring that fraction to lowest terms.

Most times, you can put a percent over 100 to create a fraction. 37% = 37/100

Multiply the numerator and the denominator by the same integer.

For percent, you move the decimal spot two places and you will get the percent. e.g (25.25=2525%) For fraction, you could create any fraction you want as long as the value of the fraction is equal to 25.25. e.g.(50.5/2) (5.05/.2)

An infinite number! To create an equivalent fraction the numerator and denominator can be multiplied by any number; one such group of numbers that can be used to create a group of equivalent factions is the counting numbers: {1, 2, 3, 4, ...} - multiply the numerator and denominator of the original fraction by 2, then 3, then 4, etc. This group is infinite in size, therefore there are an infinite number of equivalent fractions that can be written for any given fraction.

the top number of a fraction is the numetor.the bottom number fraction is a denominator .once you place the number in the divison house,you divide

This is how. Lets say the percent is 35%, then you take that 35% and use it as the top number of the fraction.35/?Now you still need the bottom number. All you do is put 100.35/100Then you simplify and it should be 7/20.So really it is the percent that you have over 100, then you simplify.* * * * *The above is a correct answer if you are given the percent. However, the question is about when you are given the fraction!Convert the fraction to a decimal by the method of long division and then multiply by 100.For example,3/7 = 0.42857 (approx)Then, multiplication by 100 gives 42.857% approx.

No. The reason you can multiply a fraction by (x/x) to find an equivalent fraction is because for almost any x, (x/x) = 1. This is not the case for zero. Zero divided by zero does NOT equal 1, so multiplying the fraction by a value not equal to 1 will create a different fraction.

Do the division. 27/48 = 27 divided by 48 = 0.5625

It's just a number divided by another number. To create a fraction on a calculator without a fraction button, you just divide the numerator by the denominator. For example, the fraction 4/9 is equivalent to 4 ÷ 9 on a calculator.

Multiply the decimal by 100 as for example 0.75 = 75%

The question requests a vague answer: does the questioner seek the answer as a percent or as a fraction? Regardless ... 16 is the 'base' number, so simply create a fraction with 16 as the denominator and the other number (which you want to find the fraction or % of 16) as the numerator: 24/16 24/16 can be reduced, as a fraction, to 3/2 (or 'three halves'), which is (as a compound number) 1 1/2 (or one and one-half, sometimes called 'half again'). As a percentage, this would be 150%.

you take the decimal and change it into a percent by moving the decimal 2 times to the rightDivide by 10034% = 0.34

For the first fraction, divide the give denominator into the LCD, take that result and multiply by the given numerator to create a new numerator for the LCD. Repeat for each fraction.

6/42 is the same as 1/7. To create an equivalent fraction, either multiply or divide the numerator (top number) and denominator (bottom number) of a fraction by the same number. In this case, I divided the numerator and denominator by 6.

The equivalents to 1/3 include 2/6, 3/9, 4/12, and 5/15. Any fraction created by multiplying both the numerator and denominator by the same integer will create an equivalent fraction. For fractions that are not in their simplest form (such as 4/16) you can also form equivalent fractions by dividing the numerator and denominator by the same number (4/16 = 2/8 = 1/4).

Multiplying the top and bottom by the same number will create an equivalent fraction.Examples:by 2:5/11 = (5x2)/(11x2) = 10/22 by 3:5/11 = (5x3)/(11x3) = 15/33 by 528:5/11 = (5x528)/(11x528) = 2640/5808

5/7 is a fraction in its simplest form. To create an equivalent fraction it is necessary to multiply both the numerator and the denominator by the same integer. The opposite is also true. To reduce an equivalent fraction to its simplest form, it is necessary to divide both the numerator and the denominator by the same integer. 20/28 is an equivalent fraction of 5/7. It is possible to reduce 20/28 to 10/14 by dividing both the numerator and the denominator by 2, but that is not the simplest form. 10/14 can be reduced to 5/7 by dividing both the numerator and the denominator by 2 again. To ensure that an equivalent fraction is reduced to its simplest form, it is necessary to divide by the largest factor that is part of both of them. Another term for this the Greatest Common Factor, or GCF.

17.6 : 10. 4 - Multiply by 10 to remove the figures after the decimal point. 176 : 104 - Divide by 8 to simplify. 22 : 13 A ratio can be expressed as a fraction. (e.g. 22/13) When simplifying a ratio, perform the same procedures as when simplifying a fraction to create an equivalent fraction.

3/4 = 6/8 = 9/12 = 12/16......and so on As the numerator and denominator have no common factors then the fraction cannot be simplified. The only way therefore to create equivalent fractions is to multiply both the numerator and denominator by the same number. In the examples shown we have multiplied the original figures by 2, 3 and 4.

Since the number 310 is an integer, it does not really have a fractional equivalent, although I could create a fraction that would simplify to 310, for example, 620/2 or 930/3.

Yes, a tenth is equal to 10/100 which is 10%. There are 10 parts to create 1 out of a tenth so this again proves it is 10%.

Multiply the numerator and the denominator by the same integer.
