## Add & Subtract Fractions

## Explanation

ADDING FRACTIONS:

STEP 1: Make sure the denominators ( bottom numbers ) of the fractions are the same.

STEP 2: Then you add the numerators ( top numbers ) and put the answer above the denominator.

STEP 3: After that, you simplify ( if you need to ).

SUBTRACTING FRACTIONS:

STEP 1: Make the denominators ( bottom numbers ) the same by finding the LCM

STEP 2: Subtract the numerators ( top numbers ) and put the answer over the denominator.

STEP 3: Then, simplify the fraction ( if you need to ).

## EXAMPLE

## MULTIPLYING FRACTIONS

## EXPLANATION

STEP 1: Multiply the numerators of the fractions.

STEP 2: Multiply the denominators.

STEP 3: Simplify and/or turn it into a mixed number ( if you need to ).

## EXAMPLE

## DIVIDING FRACTIONS

## EXPLANATION

STEP 1: Keep the first fraction the same.

STEP 2: Change the division sign to a multiplication sign.

STEP 3: Flip the second fraction ( the flipped fraction is called a reciprocal ).

STEP 4: Multiply the first fraction by that reciprocal.

STEP 5: Simplify the fraction and/or turn it into a mixed number ( if you need to ).

## EXAMPLE

## MULTIPYING DECIMALS

## EXPLANATION

STEP 1: Multiply the decimals just like regular multiplication.

STEP 2: Count how many numbers are to the right of the decimal in the equation.

STEP 3: Count that many places over on your solution and put in your decimal.

## EXAMPLE

## DIVIDING DECIMALS

## EXPLANATION

STEP 1: Move the decimal to make the divisor a whole number.

STEP 2: Move the dividend's decimal as many places as you moved the divisor.

STEP 3: Divide regularly.

STEP 4: Bring the decimal up to your solution.
