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.
