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 2nd 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 2nd 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.
