How do you muliply a fraction?

In order to multiply fractions, simply multiply the numerators with numerators and the denominators with denominators to get the product. If possible, reduce the product in its lowest terms. Example: 2/3 X 12/5 = (2 X 12) / (3 x 5) = 24/15 = 8/5.


How do you multiply a fraction with a fraction?

The numerator of the answer is the product of the two numerators.The denominator of the answer is the product of the two denominators.You should check whether the answer can be simplified.So, for example, 2/3 * 5/7 = (2*5)/(3*7).


How you multiply fractions?

Best shown with an example. 2 2/3 X 4 1/5 #1 Convert to improper(top heavy) fractions. 8/3 X 21/5 #2 cancel down (reduce) were possible. In this case by '3' 8/1 X 7/5 #3 multiply the numerators(top) and multply the denomiaotor(bottom) and place the numerator over the denomiator 56/ 5 #4 Convert to a mixed fraction 11 1/5 The answer. !!! Hope that helps!!!!


How do you multiply fractions by itself?

that is called squaring. write the fraction twice and multiply numerators and denominators. 2/3 x 2/3 = 4/9


How many proper fraction in lowest term have denominator that is one of the counting number 1 to 9?

For a _positive_ fraction to be proper and in lowest terms, the numerator must be less than the denominator and be relatively prime. For denominator 1: 0 possible numerators. For denominator 2: 1 possible numerator. For denominator 3: 2 possible numerators. For denominator 4: 2 possible numerators. For denominator 5: 4 possible numerators. For denominator 6: 2 possible numerators. For denominator 7: 6 possible numerators. For denominator 8: 4 possible numerators. For denominator 9: 6 possible numerators. Adding all of them together gives 27 positive proper fractions in lowest terms. Symmetrically, there are 27 negative proper fractions in lowest terms. Also, 0/1 is in lowest terms by the above definition. So in total, there are 55 proper fractions in lowest terms with denominator being an integer from 1 to 9.


What happens to the denominator when you add fractions?

You must find a common denominator. You figure out the smallest number that all of your denominators are divisible by. If you have to multiply the denominators by 2, you must multiply the numerators by 2, then add the numerators together, and write above the common denominator. If you have to multiply one denominator to equal the other denominator, then you must multiply the numerator above that denominator, and finally add up the numerators and place above the common denominator. Then reduce the answer to its smallest fraction.


When you multiply fractions do multiply the denominator?

Yes the numerators are each multiplied and the denominators are multiplied: For example, 1/5 * 2/3. then it would be (1*2) / (5*3) or 2/15


How do you multiply fractions it is on my math homework?

You multiply the 2 numerators to get the new numerator. You multiply the 2 denominators to get the new denominator. (The numerator is the number on top, the denominator is on the bottom) Example: 1/2*3/4 the numerators are 1 and 3. 1*3=3=new numerator the denominators are 2 and 4. 2*4=8=new denominator Answer:1/2*3/4=3/8


What are the rules for multiplying fractions?

When multiplying 2 fractions, we multiply the two numerators together and the two denominators together.


How do you multiply fractions with different denominators?

To multiply fractions, multiply the numerators together and the denominators together. For fractions a/b and c/d, the answer will be (a x c) / (b x d). Then simplify if possible. Numerical example : 2/5 x 3/8 = (2 x 3)/ (5 x 8) = 6/40 which equals 3/20
