definition of multiplying fractions?
Fractions and decimals are usually rational numbers. Besides, multiplying rational and irrational numbers is also similar.
When multiplying 2 fractions, we multiply the two numerators together and the two denominators together.
step by step
Fractions are multiplied by multiplying numerator by numerator and denominator by denominator. The fractions may be simplified before multiplying. Whole numbers have the understood denominator of 1. Read this lesson on multiplying fractions if you need help on how to multiply fractions.you multiply the denomanators and the top number then multiply the whole #s then reduce your answer if you can. an example would be 3 8/9X6 8/9= 18 64/81 get it now?
It depends on the specific problem. If you have an equation that involves fractions, quite often you'll need to multiply them.
if you have mixed numbers you make them into improper fractions before you multiply
It is similar because when you divide fractions you are technically multiplying the second number's reciprocal. (Turning the fraction the other way around)
Multiplying by a reciprocal
no you do not
There are many sites available that offer worksheets for practice in multiplying fractions. Here is the address of one of them: www.math-aids.com/Fractions/Multiplying_Fractions.htm.
After you're done multiplying, the GCF will help you determine the simplest form of the answer.
Adding and subtracting fractions can ONLY be done if the denominators are the same; then the calculation is done by adding or subtracting the numerators. Multiplying (and dividing) fractions does not require the denominators to be the same. To divide by a fraction the divisor is inverted (the original numerator becomes the new denominator and the original denominator becomes the new numerator) and then the fractions are multiplied. Multiplying fractions is achieved by multiplying the numerators together AND multiplying the denominators together. A whole number is the same as a fraction with the whole number as the numerator and a denominator of 1, so when multiplying by a whole number the denominator is multiplied by 1 (leaving it the same) and the is multiplication is effectively just multiplying the numerator by the whole number.
No you do not.
Multiplying fractions is the easiest operation you can do with them. Nothing complicated is required, just multiply the top two and the bottom two. Simple as that!
When adding and subtracting unlike fractions, it is necessary to find the LCM of the denominators, called the least common denominator. Once you have found the LCD, you can convert the fractions to equivalent fractions with a common denominator and proceed with the adding and/or subtracting. Finding an LCM will have no effect on multiplying fractions.
