Use a common denominator to write a equivalent fraction for each fraction

Multiplying Fractions:

1. Make sure you're working with two fractions.
2. Multiply numerator x numerator, then multiply denominator x denominator.

Dividing Fractions:

1. Make sure you're working with two fractions
2. Flip the second fraction upside down.
3. Change the division sign into a multiplication sign.
4. Multiply top x top and bottom x bottom.

Converting Mixed Numbers into Improper Fractions:

1. Convert mixed numbers into improper fractions.
2. Take the whole (non-fraction) number and multiply it by the denominator.
3. Add that answer to the numerator.
4. Put that amount over the original denominator and you will have an improper fraction.

Method for Adding and Subtracting Fractions:

1. Find the lowest common denominator (bottom number). For both adding and subtracting fractions, you'll start with the same process.
2. Multiply fractions to match the lowest common denominator.
3. Add or subtract the two numerators (top number) but NOT the denominators.

Yes but where are the fractions?

If we have no pizza, and divided it between you and me, how much do we get? ZERO.

However, you want equivalent fractions to 0/2. To get an equivalent fraction, you multiply the numerator (the number on the top) and the denominator (the number on the bottom) by the same number.

So we can multiply the top and bottom by 2.

0 x 2 = 0
2 x 2 = 4

So an equivalent fraction would be 0/4.

Good luck.

The denominator is that number on the bottom of a fraction, so with 2 different fractions you want to get them in a form where they have the same denominator. Often you will be trying to find the lowest common denominator.

The usual procedure is to multiply one denominator into the top (numerator) of the other fraction. Then repeat this process with the denominator of the second fraction multiplied into the numerator of the first fraction. Then multiply the 2 denominators together and the result is the denominator now of both fractions.

Eg 2/3 and 5/7 become

14/21 and 15/21

Sometimes further simplification is possible where one fraction has a denominator which is a mltiple of the other. eg

2/3 and 5/6

In this case you only need to multiply on the first fraction

4/6 and 5/6

Reduce 4/8 to the common denominator of 4, by dividing the numerator by 4 (4 / 4 = 1) and the denominator by four (8 / 4 = 2)

Subtract to find the answer 2/4 - 1/4 = 1/4

A number with a periodic decimal representation cannot be equivalent to a fraction with denominator 10 (or a multiple of 10) except if the repeating decimals are zeros.
0.454545...=45/99=5/11

Equivalent fractions are fractions that have the same value.
2/6 is equivalent to 4/12, 8/24, 16/48. From a given fraction you can generate an infinity of other equivalent fractions by multiplying the numerator and the denominator by the same integer.
All the equivalent fractions can be generated from a single one, namely the fraction that has the lowest numerator and denominator. This one is called the reduced fraction or the reduced form of the fraction.

When you have a fraction you can try to simplify it: You look for a common factor in the numerator and the denominator and you divide both by it. Keep doing so until you can no longer find common factors to cancel out. The last fraction whose numerator and denominator have no common factor is the reduced form of the family of equivalent fractions.

Now, what is you question??.

It is simple. 36=4x9 and 63=7x9. The number 9 is a common factor in both numbers. You can simplify the fraction by dividing both the numerator and the denominator by 9.
36/63=(4x9)/(7x9). You can rewrite the fraction as (4/7)*(9/9)=4/7 because 9/9=1.
The reduced fraction equivalent to 36/63 is 4/7. Since 7 and 4 have no common divisor you cannot reduce the fraction further.

A quantity into which all the denominators of a set of fractions may be divided without a remainder.
