Is there a trick to multiplying mixed numbers?
you have to turn them into improper fractions before you multiply them.
Why is it necessary to convert mixed fractions to improper fractions before multiplying or dividing?
Multiplying mixed fractions is very cumbersome and prone to errors. Therefore, it is prudent to convert them to improper fractions. Once that is done, you may simply find the product of all the numerators and divide that by the product of all the denominators. Then you convert back to a mixed number. And there are lots of tricks -- like "canceling out" -- that you can do to simplify the multiplication. Unfortunately, those techniques are very difficult to demonstrate here. It would not be even if it is not an improper fraction and that's why you have to convert
When asked to find the sum of two mixed numbers with different denominators you should before you add?
Convert the fractions into equivalent fractions with the same denominator. In actually adding mixed numbers, it is easier to convert the mixed numbers into improper (top heavy) fractions, do the addition, simplify the resulting fraction and convert any resulting improper fraction back into a mixed number.
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.
What is cross canceling in dividing fractions?
Cross canceling is a way to simplify or reduce fractions before multiplying them. For example, 2/4 x 1/6 can be reduced to 1/4 x 1/3 by cross canceling.
How is multiplying mixed numbers different than multiplying fractions?
if you have mixed numbers you make them into improper fractions before you multiply
Is there a trick to multiplying mixed numbers?
you have to turn them into improper fractions before you multiply them.
Why do you change mixed numbers to improper fractions before multiplying and dividing?
Because common denominators allow adding and subtracting of numerators. Improper fractions also have simplified rules over mixed numbers when performing multiplication and division.
Why do you have to change a mixed number to an improper fraction before multiplying mixed numbers?
You don't.
You read on the fraction chart that the proper shape for multiplying fractions is fraction form what does that mean?
In the context of multiplying fractions, the term "proper shape" refers to the format in which the fractions are written before performing the multiplication operation. When multiplying fractions, it is essential to ensure that the fractions are in their simplest form, with no mixed numbers or improper fractions. This simplifies the calculation process and allows for easier manipulation of the numerators and denominators during multiplication. Therefore, maintaining the fractions in fraction form ensures accuracy and efficiency in the multiplication process.
Explain why you do not have to change mixed numbers to improper fractions before you find the LCD?
because they are going to have the same denominator.

What is a general rule for multiplying fractions and whole numbers?
A general rule for multiplying fractions: You shall not multiply the denominator by the whole number,only the numerator.Another rule is you shall make the whole number as a fraction by putting the whole number as the numerator and 1 as the denominator before multiplying it.
How do you solve 1 and one third times 2 and one fourth times 3 and one fifth?
This can be done in different ways, but it is probably easiest to convert all the mixed fractions to improper fractions first. Then multiply all the numerators, and all the denominators. You can do simplifications either before multiplying, or after multiplying.
Why do you think it is helpful to convert mixed numbers into fractions before multiplying or dividing?
So that you can get your answer more faster and you don't need to do a lot of work
How do you divide mixed numbers with like denominators?
Written as improper fractions, divide the numerators (converting any resulting improper fraction to a mixed number if required).However, I would rather not remember this short cut as it could result in being used inappropriately (when the denominators are different), but instead stick to using the standard method, writing out the calculation in full and cancelling down before doing the actual multiplications.The same way as mixed numbers without like denominators:Convert the mixed numbers into improper (top heavy) fractions.Invert (turn upside down) the divisor.Multiply the fractions together (by multiplying the numerators together and the denominators together).However, with the same denominators, in inverting the divisor it will mean that its numerator is the same as the denominator of the [original] dividend and so will cancel, leaving the result as the numerator of the first improper fraction over the numerator of the second - dividing the improper fractions' numerators.
