A fraction is equivalent to another if the ratio of the numerator and denominator is the the same in both. To find an equivalent fraction, multiply or divide the numerator and denominator by the same ammount.

You get the same answer both times.

That depends what you want to do. If you multiply both the numerator and the denominator by the same number, you get another fraction that stands for the same number - an equivalent fraction. For example, if you have the fraction 1/2, you multiply top and bottom by 2, to get 2/4. 2/4 is simply another name for 1/2.

Multiply the numerator and the denominator by the same integer.

Cross multiplication is when you multiply the denominator of a fraction by the numerator of another fraction. Before you cross multiply you want to see if you can simply the fractions.

simply divide the numerator and denominator by two. if they are not even, find another multiple that fits both the numerator and denominator. once you have simplified the fraction, just turn the denominator into 100 (make sure you multiply or divide only) then multiply or divide the same number by the numerator, then you divide it by 100 and you get your answer!!!!!

You may be referring to the rule for dividing fractions. To divide one fraction by another, you invert the second fraction (exchange numerator and denominator), and multiply instead.

equivalent of 4 over 28 is 1 over 7. you divide by 4 both numerator and denominator or multiply by the same number both numerator and denominator

Multiply both the numerator and the denominator of the fraction you already have by the same number, and you'll get another fraction that's equivalent to it.

Simply change the numerator and you will have another - different - fraction wit the same denominator.

You cannot because it is not true - unless the fraction is 0/n (for any n) or n/n = 1.

Any real number can be the denominator in a fraction. A fraction is a way of expressing one number (the numerator, the "top" number in a fraction) by another (the denominator, "bottom number.") So it is possible to have a denominator of 100.

Write the conversion as a fraction. Then multiply the numerator and denominator across, then cancel any units that are both top and bottom.

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.

The result (which should be simplified) is another fraction of some kind: * a proper (or vulgar fraction) with the numerator (top number) less than the denominator (bottom number); * an improper fraction with the numerator greater than the denominator which can be converted into a mixed number; or * an integer (whole number).

To divide a fraction by another fraction, you multiply by the reciprocal - that is, in the second fraction you exchange numerator and denominator, while at the same time changing the division to a multiplication.Example: 5 divided by one-and-a-half5 / (1 1/2) = 5 / (3/2) = 5 x (2/3)To divide a fraction by another fraction, you multiply by the reciprocal - that is, in the second fraction you exchange numerator and denominator, while at the same time changing the division to a multiplication.Example: 5 divided by one-and-a-half5 / (1 1/2) = 5 / (3/2) = 5 x (2/3)To divide a fraction by another fraction, you multiply by the reciprocal - that is, in the second fraction you exchange numerator and denominator, while at the same time changing the division to a multiplication.Example: 5 divided by one-and-a-half5 / (1 1/2) = 5 / (3/2) = 5 x (2/3)To divide a fraction by another fraction, you multiply by the reciprocal - that is, in the second fraction you exchange numerator and denominator, while at the same time changing the division to a multiplication.Example: 5 divided by one-and-a-half5 / (1 1/2) = 5 / (3/2) = 5 x (2/3)

To convert a fraction to an equivalent fraction, you multiply, or divide, both parts (numerator and denominator, that is, top and bottom), by the same non-zero number. Thus, for example, if you have a fraction 3/5, you can multiply top and bottom by 2 to get 6/10, or by 3 to get 9/15, etc.

When the numerator and denominator have another common factor besides ' 1 '.

To get a fraction of another fraction you have to multiply the fractions. To multiply fractions, just use this simple algorithm: Step 1-Turn all whole numbers and mixed numbers into improper fractions. Step 2-Multiply the numerators of the 2 fractions. The answer to that problem will be the numerator of the answer. Step 3-Multiply the denominators of the 2 fractions. The answer to that problem will be the denominator of the answer. Step 4-Reduce.

To convert a fraction to a percent, you first divide the numerator by the denominator. And then multiply by 100, which moves your decimal point two places to the right.Another way to do it, or check your answer, is to make the fraction equivalent to a denominator of 100. So if you were to convert 8/25 to X/100, your new numerator would be the percentage.

If you mean to divide one fraction by another, the easiest is to multiply your numerator fraction by the reciprocal of your denominator fraction. For example, if: x = (a / b) / (c / d) then: x = (ad)/(bc)

To divide one fraction by another, you multiply the first fraction by the reciprocal of the second - that is, you exchange numerator and denominator in the second fraction, then multiply. Therefore, 13/3 divided by 8/3 is the same as 13/3 times 3/8.

So you can answer question 1 in your homework. Any number times 1 is equal to the original number. When we simplify a fraction or change a fraction to find a common denominator so we can add or subtract if from another fraction we do not want to change it's value. We multiply ( or divide it ) it by one essentially. Remember 5/5 = 2/2 = 7/7 = 1.

A fraction in which the same quantity is expressed one way in the numerator and another way in the denominator.

Near enough what you describe in the question - except that you say "on" instead of "one". It has no special name.
