How is multiplying mixed numbers different than multiplying fractions?
if you have mixed numbers you make them into improper fractions before you multiply
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.
When multiplying use fraction notification we form products in the numerator and the denominator but do not immediatily calculate the product?
That is correct. It is easier to simplify the fraction before multiplying all the factors in the numerator and the denominator.That is correct. It is easier to simplify the fraction before multiplying all the factors in the numerator and the denominator.That is correct. It is easier to simplify the fraction before multiplying all the factors in the numerator and the denominator.That is correct. It is easier to simplify the fraction before multiplying all the factors in the numerator and the denominator.
What do you do first with the mixed numbers before multiplying?
What you are to do is the mixed numeral is converted to a improper fraction. To do this just simply multiply the denominator with the whole number then add that with the numerator. With that number you end up with will be the numerator over whatever the denominator was. Then you can multiply the fractions.(I'm not a good explainer but i hoped i helped a bit)
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 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.
How do you change mixed numbers before multiplying improper fractions?
To convert a mixed number to an improper fraction, multiply the denominator by the whole number, add that total to the numerator and put the whole thing over the original denominator. 3 and 1/7 = 22/7
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.

Why do you change mixed numbers to improper fractions before you divide?
Well unless the whole number can be divided evenly by the divisor, a fraction would be left over before dividing the fraction by the divisor. It is much easier in these cases to create a top-heavy fraction
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 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.
