A common denominator is 32.

An infinite number of combinations of fractions can be aded together to equal three fourths.

When you want to add fractions that have different denominators, you have to convert them into fractions that do have the same denominators. So for example, how much is a half plus a third? Both of these can be converted into sixths, so one half equals three sixths, and one third equals two sixths. Three sixths plus two sixths equals five sixths. That's the answer. If you have three fractions with different denominators, the procedure is the same. Convert all three into fractions with the same denominators, then add them.

find a common denominator for all three and then add all of the numerators together and keep the same denominator

it stay the same when you subtract fractions and when you add fractions.

1/4 + 2/4

Fractions! Otherwise you don't have anything to add.

In fractions, you can NEVER add or subtract

No.

-- Find a common denominator. (It will be a number of which all three denominators are factors. The best choice is their least common multiple.) -- Change the fractions to their equivalents with the common denominator. -- Then add their numerators to get the numerator of their sum.

Change them into mixed numbers and add the integers and fractions together ensuring that the fractions have a common denominator.

The three types of fractions are mixed, improper, and proper fractions.

add by adding

You need a common denominator in order to add or subtract fractions.

There are three types of fractions that are used in mathematics. The three types of fractions are, mixed fractions, proper fractions, and improper fractions.

The denominators are different, so find the equivalent fractions using the LCD , then add the fractions with the denominators.

with a calculator

No.

Change them to like fractions and proceed.

irregular fractions! ex. if the equation is 2 3/4, you would multiply 2*4, then add three. that is your numerator, denominator will stay the same. it will =11/4

Because you can't add or subtract fractions that have different denominators. Making them like fractions, by multiplying so the denominators are the same, you can add and/or subtract them.

Make the fractions equivalent then subtract

The usual rules of addition of fractions apply.
