you have to turn them into improper fractions before you multiply them.
Simplicity of calculation
the fractions have different denominators
First change the mixed numbers into improper fractions by multiplying the denominator and the whole number and add the product to the numerator in the mixed numbers and then multiply the numerators and the denominators and divide the numerator by the denominator of the product.
No. The commutative and associative laws are valid for any real numbers.
when you add mixed numbers you have a whole number but adding fraction does not.
Mixed numbers cannot be turned into proper fractions, but they can be made into improper fractions by multiplying the integer (# on the side) by the denominator (bottom), and then adding that number to the numerator (top).
Mixed fractions can't become whole numbers.
First you change them into improper fractions. Then you multiply the numerator and the denamanator straight across. ;)
what is dividing fractions and mixed numebers
In case of Proper fractions the numerator is lesser than the denominator. Whereas in case of improper fractions and mixed fractions the numerator is greater than denominator.
Change each mixed fraction to an improper fraction. Do this by multiplying the denominator by the whole number next to the fraction and then adding the numerator to the product you get. Once you do this, multiply fractions normally.
To combine the fractions or subtract the fractions. Same method with mixed numbers.
So that you can get your answer more faster and you don't need to do a lot of work
Change the mixed numbers to improper fractions, find a common denominator and proceed.
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.
you cant divide mixed numbers
Mixed numbers can be converted to improper fractions. Then, it is exactly the same as adding proper ones.
change the mixed # into a fraction
Fractions can be converted to decimals, percentages or mixed numbers.
It helps with adding and multiplying fractions sometimes. Its simpler to multiply 3/7 x 9/7 than 1 2/7 x 3/7.
Mixed numbers and mixed fractions are the same thing.
Mixed numbers are larger than proper fractions.
