How do you deal with improper fractions?
You need to learn how to convert from improper fractions to mixed fractions and vice versa; however, for most other operations, such as compare, add, subtract, multiply, and divide them, it really doesn't make much difference whether the fraction is proper or improper.
How do you multiply a mixed fraction by a whole number?
You would turn the mixed number into a fraction by multiplying the whole number(the one in the mixed fraction) by the denominator and then you add the numerator to the product. You would then put that number you get and out it over the denominator. For the other whole number, you would put it over one and multiply the two fractions!
How do you add a fraction without a common denominator?
You have to make a common denominator between them, otherwise you can't. See if they have similar factors, or if you can't find any easily, cross-multiply and multiply the numerator and denominator of one side by the denominator of the other side and do the same thing to the other side with the denominator of the other fraction!
Adding mixed numbers with unlike denominators?
First convert the mixed numbers into "top heavy (or "improper) fractions". Now multiply each of the improper fractions by each other - this makes the denominators the same. Now you can add both the fractions together (and cancel down if necessary).
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.
How do you turn improper fractions to mixed numbers?
You multiply the denominator by the whole number and then you add the top half of the fraction to that number. You put the number you get over the original denominator and that is your answer.actually,you divide the numerator to the denominator or the other way around
How do you times mixed fractions?
My strategy for multiplying mixed fractions: what you need to do is turn the mixed number into an improper fraction before you do any thing else. to do that you need to multiply the denominator with the whole number then add the numerator. now that number will be your numerator the denominator stays the same then you do the same to the other mixed fraction turn it into an improper fraction then once both are like that you multiply the numerators together to find the numerator then you multiply the denominators together to get the denominator then simplify your answer to get the right answer.
How is dividing mixed numbers the same as dividing fractions?
A mixed number can be converted into an improper fraction. Mixed numbers as improper fractions can be divided just like any other fraction. To convert a mixed number to an improper fraction multiply the whole number by the denominator and add the original numerator to give the new numerator and put this over the original denominator.
How do you convert fractions to other equivalent fractions?
multiply the numerator and the denominator by the same number, or divide each side by a common factor.
What is the definition of cross product?
taking two fractions. and cross multiply. all fraction has a numerator (top number) and a denominator (bottom number). multiply the numerator to the other fraction's denominator and the denominator to the other fraction's numerator to get the product.

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 can you tell if two fractions are equivalent?
Two fractions are equivalent if the fully simplified fractions are equal. If you can multiply the fraction with the smaller numerator and denominator by the same value to equal the second fraction. For example the fractions 3/4 and 9/12. The nominator and denominator, 3 and 4 have both been multiplied by 3 to equal 9/12. Cross multiply. If the products are equal, the fractions are equal. Cross multiplying means to multiply each numerator of one fraction with the denominator of the other fraction.
How many fractions are equivalent to 4 5ths?
There are an infinite number of proper fractions equal to any other fraction - as long as you multiply the numerator and denominator by the same number, the fractions will be equivalent.
