Well you don't you just multiply right across lets say the problem was 1/4 * 1/2 it would 1/8.So you multiply across.

How do you add two fractions with a different denominator?
You add two fractions with a different denominator by multiplying the denominators by a number that will make them equal. Be sure to multiply the numerator by that number too.
How do you multiply fractions that have the same denominator?
you don't do anything. you just multiply it together unless on the numerator you can reduce it with one of the denominators. ================================= On the remote chance that perhaps you find the first answer unclear, here's another explanation: To multiply two fractions: -- Multiply their numerators. That product is the numerator of the answer. -- Multiply their denominators. That product is the denominator of the answer. -- Now you have the answer. It may be possible to simplify it (reduce it to lower terms). It's not necessary for the original two fractions to have the same denominator. Just follow the same two easy steps to multiply the fractions, whether their denominators are the same or different.
How to find thirteen fiftieths of seven tenths?
You multiply the two fractions. To multiply two fractions, the numerator of the result is the product of the numerators, and the denominator of the result is the product of the denominators.
How to add fractions having similar numerators but different denominators?
The first step, to add, subtract, or compare fractions, is always to convert the fractions to equivalent fractions, that all have the same denominator. You can use one of several techniques to get the LEAST common denominator, or simply multiply the two denominators to get a common denominator (which in this case may, or may not, be the smallest common denominator).
When you multiply two fractions do you need to find a common deniminator first?
No. Fractions don't need the same denominator in order to multiply them. The numerator of their product is simply the product of their numerators, and the denominator of their product is just the product of their denominators.
How do you add two fractions with a different denominator?
You add two fractions with a different denominator by multiplying the denominators by a number that will make them equal. Be sure to multiply the numerator by that number too.
How do you change a fraction so they have the same denominator?
First, find a common denominator for the two (or more) fractions. Then, for each fraction, multiply numerator and denominator by the same number (different numbers for different fractions, though), to convert to the common denominator.
How do you put different fractions in increasing order?
Option 1: Find a common denominator for the two fractions. It need not be the least common denominator; for example, for two fractions, if you just multiply the two denominators, you get a common denominator. Convert all the fractions to the common denominator. Then you can compare. Option 2: Convert each fraction to decimal, by dividing the numerator by the denominator. Then you can compare the decimals.
How can you find common denominator for two unlike fractions?
multiply the two denominators

How do you make the denominator the same?
To make the denominator of two fractions the same, you multiply numerator and denominator of one fraction of the fractions by the same number. You may also have to multiply numerator of the other fraction by a different number.For example, to add 1/8 + 1/10, you have to convert to a common denominator; the lowest common denominator is 40, but any common denominator will work (for example, 80 which is simply the product of the two).To convert 1/8 to a fraction with a denominator of 40, multiply numerator and denominator by 5. To convert 1/10, multiply numerator and denominator by 4. The result is:5/40 + 4/40To make the denominator of two fractions the same, you multiply numerator and denominator of one fraction of the fractions by the same number. You may also have to multiply numerator of the other fraction by a different number.For example, to add 1/8 + 1/10, you have to convert to a common denominator; the lowest common denominator is 40, but any common denominator will work (for example, 80 which is simply the product of the two).To convert 1/8 to a fraction with a denominator of 40, multiply numerator and denominator by 5. To convert 1/10, multiply numerator and denominator by 4. The result is:5/40 + 4/40To make the denominator of two fractions the same, you multiply numerator and denominator of one fraction of the fractions by the same number.

How do you subtract two fractions?
You have to find a common denominator, multiply them, subtract them and then simplify if you need to.

No. Fractions don't need the same denominator in order to multiply them. The numerator of their product is simply the product of their numerators, and the denominator of their product is just the product of their denominators.
How do you do cross multiplication?
Take the two fractions and put them side to side and multiply the numerator and the numerator and the denominator by the denominator and simplify if needed
How do subtract two fractions with different denominator?
First find the lowest common denominator and then adjust the fractions accordingly before subtracting the numerators
