i think you take the problem and turn it in to a improper fraction. estimate. add. Vola!
Improper fractions can't become proper fractions.
Mixed numbers can be converted to improper fractions. Improper fractions can be added the same way proper fractions are.
Change them into mixed numbers and add the integers and fractions together ensuring that the fractions have a common denominator.
turn them into improper fractions
Proper fractions are less than 1. Improper fractions are greater than 1. For a proper fraction to become an improper fraction, you would have to add a quantity that would make it greater than 1.
you cant turn improper fractions into fractions but you can turn fractions into mixed numbers. to do this you see how many times the denominator goes into the numerator. for example: if your improper fraction is 7/5, 5 goes into 7 one time but there is two left over. you just put that two on top of your denominator and it turns out 1 and 2/5.
Divide the numerator by the denominator
here is an example if you want to convert an improper fraction 5 and 3\4 you would multiply the denominator 4 and the whole number 5 and then you add 3 the nominator so the answer would be 23 over 4
To find the sum of two mixed numbers, turn the mixed numbers into improper fractions (multiply the base with the denominator and add the numerator), then add the two fractions. To add the two fractions, find the LCD (lowest common denominator) and add the two numerators, but leave the denominators the same.
he fact that they are improper is irrelevant. Re-scale the fractions so that they have the same denominator and thenadd or subtract as required.
