If a fraction (like three and three quarters) is made up of a whole number part and a fraction part and you want to calculate with it it is usually best to change it to improper fraction".
Three and three quarters would become 15/4 because it has 15 quarters in it.
Such a fraction is sometimes called "top heavy".
If you wanted to divide 3 and 3/4 by 1 and 1/5, they would be changed to15/4 and 6/5 The rule for dividing by a fraction is to "turn it upside down and multiply" instead. So if you wanted to divide the 3 and 3/4 by the 1 and 1/5 you would then "invert" the 6/5 to 5/6 and then multiply 15/4 by 5/6. Then you can cancel the 15 and the 6 both by 3 leaving you with 5/4 x 5/6 = 25/8 which produces 3 whole ones and 1/8
If you wanted to multiply them always look for the chance to "cancel" to make numbers smaller. So starting with 3 and 3/4 multiplied by 1 and 1/5 we change the first into 15/4 and the second to 6/5. Now you can15 and the 5 by 5 giving you 3 and 1 instead. Similarly cancel the 4 and the 6 by 2 giving 2 and 3 instead. Multiplying the numerators gives9, and multiplying the denominators gives 2, so now we have 9/2 which is 9 halves which is 4 whole ones and 1/2 for the final answer.

How do you calculate an average with fractions?
The same way you calculate averages with whole numbers: Add up all the fractions and divide by the number of fractions there are.
How do you do quotient with fractions?
if you can divide whole numbers, turn the fraction into a whole number by finding its equivalent and replacing the fraction with that equivalent. Then divide the new number which should be whole and you have your answer.
What do fractions help with?
Fractions help with numbers that are not whole numbers.
Where are the fractions?
The fractions are when you divide a whole number into equal parts
How do you divide whole fractions with simple fractions?
It is simple all u really do is divide reguarlly.......

Are fractions and decimals numbers that represent parts of a whole?
yes they do and fractions also represent divide like if you had 1/2 you would have half of a whole!

Are fractions whole numbers?
No. All fractions are not whole numbers, but all whole numbers are [improper] fractions (with a denominator of 1).
How do you reduce fractions with whole numbers?
first you divide the numerator by whatever number and the denominator by the same number and that is your answer.
