Steps for Solving Fraction and Percent Problems

Good morning!  I've typed out all the steps for solving fraction and percent problems to help the kids study tonight.  We have practiced all of this in class.  Here is the list to help at home.

Steps for Solving Fraction and Percent Problems

Adding Fractions and Mixed Numbers

Step 1:  Change the fractions to equivalent fractions with like denominators.

Step 2:  Add.

Step 3:  Simplify if the numbers in the new fraction share a common factor.

Subtracting Fractions

Step 1:  Change the fractions to equivalent fractions with like denominators.

Step 2:  Subtract.

Step 3:  Simplify if the numbers in the new fraction share a common factor.

Subtracting Mixed Numbers

Step 1:  Change the fractions to equivalent fractions with like denominators.

Step 2:  If the top fraction is smaller than the bottom, change to mixed numbers and subtract.  If not, simply subtract the fractions you have.

Step 3:  Simplify if the numbers in the new fraction share a common factor.

Multiplying Fractions

Step 1:  Multiply the numerators.

Step 2:  Multiply the denominators.

Step 3:  Simplify if the numbers in the new fraction share a common factor.

Multiplying Mixed Numbers

Step 1:  Change the mixed numbers into improper fractions.

Step 2:  Multiply the numerators.

Step 3:  Multiply the denominators.

Step 4:  Simplify if the numbers in the new fraction share a common factor.

Dividing Fractions

Step 1:  Change the operation to multiplication and flip the 2^nd fraction upside down.

Step 2:  Multiply the numerators.

Step 3:  Multiply the denominators.

Step 4:  Simplify if the numbers in the new fraction share a common factor.

Multiplying Mixed Numbers

Step 1:  Change the mixed numbers into improper fractions.

Step 2:  Change the operation to multiplication and flip the 2^nd fraction upside down.

Step 3:  Multiply the numerators.

Step 4:  Multiply the denominators.

Step 5:  Simplify if the numbers in the new fraction share a common factor.

Finding a Percent of a Number

Step 1:  Change the percent to a decimal.

Step 2:  Multiply.

Finding a Fraction of a Whole Number

Step 1:  Change the whole number to a fraction.  E.g., 4 = 4/1

Step 2:  Multiply the fraction by the whole number.
