Why don't you have to find a common denominator when multiplying fractions?

Multiplying fractions is quite different from adding them. You just multiply the numberators and the denominators separately. You can find the common denominator if you like, but in the end (after simplifying), you'll get the same result, and the additional work of finding the common denominator and converting the fractions turns out to be unnecessary. Try it out for some fractions!

When multiplying fractions do you also multiply the denominator?
I dont know
How do you find equivalent fractions with a common denominator?
You dont really, well at least in my years of knowledge
How do you do subtract fractions?
One way you can subtract fractions is to change them into decimals, aligning the decimals vertically, then subtracting like you would with whole numbers, making sure to carry down the decimal. Another way that you can subtract fractions is to use the least common denominator (lcd). First, simplify the fractions. Then find the multiples of the denominators. When you find the multiple included in both lists that is the least, multiply the numerator and denominator by the same number in order to make the denominator into the lcd. Then, subtract the numerators and simplify the answer. Example: 2/3 - 1/2 = 4/6 - 3/6 = 1/6
Why does cross-multiplying work?
I dont know the answer
What is the difference between unlike fractions and like fractions?
that they dont looks like them

When you multiply a fractions with the same denominator will the denominator be the same?
exactly you got it you dont need help :)

How do you simplify improper fractions?
To simplify improper fractions you just have to simplify as you would with a regular fraction. Which is very easy, and if you dont know I will tell you how. How to Simplify Fractions: Divide the numerator and the denominator by a common factor. Example: 2/4=1/2 (2 is the common factor in both 4 and 2)
How do you do multiplication fraction questions?
To multiply fractions, you must simply multiply the numerators and denominators. This means, that by multiplying fractions, you are making the fractions smaller. If this does not make sense, then read the following example. Example: Equation: 2 4 _ x _ 3 6 Step 1: Multiply the numerators: 2 x 4 = 8 Step 2: Multiply the Denominators: 3 x 6 = 18 Now you have your answer! 8 _ 18!!!!
How do you do fractions with different denominators?
example: 3/4+3/8=? First find a common multiple: 8 then make sure the denominator for each is 8. To do that for the first fraction you have to multiply the denominator by 2...and whatever you do to the denominator you have to do to the numerator. so you multiply the 3 also. 3/4=6/8 since the denominator for the second fraction is already 8, you dont do anything to it/it stays the same! add across and the new equation is: 6/8+3/8=9/8 Hope it helped!
How do you find the sum of two fractions?
First you find the common denominator then add the numerators divide the numerator by the common denominator! Example: 24divided by 131 = 5r11 24 *5=???? so easier would be 25*5 wich in money is 1 25 so 24*5 +120 131-120 =11 so on top we should have 5r11 if u dont get this please update this it was written by a middle schooler! sorry if its wrong:( i know it isn't though
How do you get 40 by multiplying by 3?
