How do you add 2 fractions?

1. Step 1: Make sure the bottom numbers (the denominators) are the same.
2. Step 2: Add the top numbers (the numerators), put that answer over the denominator.
3. Step 3: Simplify the fraction (if possible)

What do you call fractions with different denominators?

From definition (1) we can say that the fractions with different denominators are called unlike fractions.

How do you add fractions and mixed fractions?

Note: The rules for adding and subtracting improper fractions are the same as working with proper fractions. Step 1: Keep the denominator the same. Step 2: Add or subtract the numerators. Step 3: If the answer is an improper form, reduce the fraction into a mixed number.

How do you change like fractions?

Step 1: Multiply the numerator of the first fraction by the denominator of the second fraction. Step 2: Multiply the numerator of the second fraction by the denominator of the first fraction. Step 3: Multiply the denominators of both fractions and take it as a common denominator for the results of step 1 and step 2.

How do you convert a mixed fraction to a fraction?

1. Step I: Find the L.C.M of all the denominators.
2. Step II: Divide the L.C.M by the denominator of the first fraction and get the quotient.
3. Step III: Multiply both numerator and denominator of the first fraction by the quotient.

How do you change unlike to like fractions?

How to Convert Unlike Fractions to Like Fractions? Unlike fractions can be converted to like fractions by finding the lowest common multiple (LCM) of the denominators first and then calculating their equivalent fractions with the same denominator.

How do you add polynomial fractions with the same denominator?

To add or subtract two rational expressions with the same denominator, we simply add or subtract the numerators and write the result over the common denominator. When the denominators are not the same, we must manipulate them so that they become the same.

How do you solve a fraction with a polynomial denominator?

To simplify a fraction with a factorable polynomial in the numerator and the denominator, factor the polynomial in the numerator and the denominator. Then reduce the fraction to lowest terms by canceling out any monomials or polynomials that exist in both the numerator and denominator.

How do you make mixed numbers into improper fractions?

Answer: To turn a mixed number into an improper fraction, multiply the whole number with the denominator of the proper fraction. Add the numerator of the proper fraction to this product to obtain the numerator of the improper fraction.
