you strike out the numbers into its lowest form but you can only bring the Numbers that are diagonal or across to its lowest terms (e.g 3/8 x 1/3 you can only bring 3 and 3 to its lowest term or 3 and 1 (they do not go into each other) or 8 and 3 (they don't go into each other) or 8 and 1 (they don't go into each other) once you bring it to its lowest term then you multiply horizontally (e.g 3/8x 1/3 the 3 and the 3 would become a 1 and a 1
so you would multiply 1x1=1 and 8x1=8 and the fraction would be

How do you Multiply three or more mixed numbers.?
Convert them to improper fractions and proceed the same way you would multiply two fractions.
How do 4th graders divide and multiply fractions?
The same way anyone else does. To multiply fractions, multiply the top numbers together and then the bottom numbers together. The two totals become the top and bottom number, respectively, of the new fraction. To divide fractions, flip the second fraction upside down and multiply it.
What are the rules of the dissimilar fractions?
I assume you mean, with different denominators. If you want to add the fractions, subtract them, or compare them (determine which one is greater), you have to convert them to similar fractions (fractions with the same denominator) first. Converting to similar fractions is not necessary, and usually doesn't even help, if you want to multiply or divide fractions.
How do you common denominators for 3.5 and 1.4?
If those are both denominators, multiply their fractions by 10/10 to get rid of the decimal points. The LCD of 35 and 14 is 70. Convert them to equivalent fractions with a denominator of 70.
How can using the GCF and LMC help you you add subtract and multiply fractions?
In order to add or subtract fractions, the denominator (bottom number) has to be the same. In order to make it the same, you find the LCM and multiply the fraction by whatever is necessary to make the denominator the LCM. FOR EXAMPLE: 1/3 + 2/5 The LCM of 3 and 5 is 15. To make the 3 in 1/3 15, you multiply the whole fraction by 5 over 5 (it simplifies to 1 so you aren't really changing the fraction by multiplying it by 1). 1/3 * 5/5 is 5/15 You multiply 2/5 times 3 over 3 using the same principle 2/5 * 3/3 is 6/15 NOW you can add 5/15 and 6/15 to get 11/15.

What is the difference between cross and across?

Why do you invert fractions?

When you multiply fractions do you multiply the denominator?
yes. you multiply the numerator and denominator
When you multiply fractions do you multiply the bottom numbers too?
Yes.
Do you ever multiply a fraction?
Yes, there are times when you multiply fractions.
How can one multiply fractions without a calculator?
You multiply the numerators across and put that as the numerator of your answer, then multiply the denominators of the fractions across the put that as the denominator of your answer. It is very easy.
What is a definition for ordering fractions?
to order fractions you can cross multiply two fractions at a time or you can convert all the fractions into decimals.
How do you Multiply 3 fractions?
Multiply the first two together and then multiply that total by the third.
