Exactly the same as you do when multiplying fractions with different denominators. -- Multiply numerators . . . the product is the numeratore of the answer. -- Multiply denominators . . . the product is the denominator of the answer.

you subtract the numerators, and leeave the denomonators alone

The denominators must be the same, the numerators can be different.

It stays the same. Only the numerators change.

this is a tricky question but the relationship between the numerators of the product is that they both fractions - and for the next question is that in some fraction their is aways going to have the same denominator that never changes or DONT CHANGE AT ALL !

first you get the denominators the same then you multiply the number you multiplied to the denominator to the numerator then you add the two numerators together and keep the denominators the same then if needed you simplify

Exactly the same as you do when multiplying fractions with different denominators. -- Multiply numerators . . . the product is the numeratore of the answer. -- Multiply denominators . . . the product is the denominator of the answer.

To multiply a fraction, you multiply the numerators and leave the denominators (assuming the denominators are the same.)e.g. 2/3 x 3/3 = 6/3 or 2If the denominators are not the same, try to find the least common multiple between the two.

First, you find the greatest common factor of the denominators. Second, you multiply the top by what you had to multiply on the bottom. Finally, you add the numerators together, NOT the denominators they stay the same, and then you would get your answer.

If denominators (bottom numbers) are the same,subtract numerators (top numbers).If not you need to make the denominators the same and then subtract numerators.

No, the LCM of the denominators.

The numerator and denominator of a product of fractions are simply the products of the numerators and denominators respectively. That is, a/b * c/d = (a*c)/(b*d). The denominators can be the same or different - that is irrelevant.

If the denominators are the same, subtract the numerators. If the denominators are different, convert them to equivalent fractions with a common denominator and subtract the numerators.

Multiply the denominators to equal numbers, then multiply by the same number for the numerator. Then solve.

Yes because the numerators add up to equal a whole number which is 1

First you have to compare the whole numbers. When the whole numbers are the same, compare the fractions. If the denominators of the fraction are the same, compare the numerators. If the denominators are different, convert them to have the least common denominators. Then compare the numerators.

You first have to convert the fractions so that the denominators are the same.
