Examples and Practice

Adding Fractions

1) Make sure the denominators (bottom numbers) are the same.

2) Add the numerators (top numbers) together.

3) Simplify if necessary.


Examples and Practice

Subtracting Fractions

1) Make sure the denominators (bottom numbers) are the same.

2) Subtract the numerators (top numbers).

3) Simplify if necessary.


Examples and Practice

Multiplying Fractions

1) Multipy the numerators (top numbers).

2) Multiply the denominators (bottom numbers).

3) Simplify if necessary.


Examples and Practice

Dividing Fractions

1) Get the reciprocal of the second fraction. Turn it over.

2) Multiply the first fraction with the reciprocal of the second fraction.

3) Simplify if necessary.


Examples and Practice

Adding Decimals

1) Keep your work neat. Write down the numbers in columns with decimals lined up.

2) Pad decimal side with zeros to end at same location (put zeros at the end of the number if necessary).

3) Use column addition to add the numbers.


Examples and Practice

Subtracting Decimals

1) Keep your work neat. Line up the decimals.

2) Pad decimal side with zeros if necessary.

3) Subtract.


Examples and Practice

Multiplying Decimals

1) Multiply normally. Ignore the decimals.

2) When finished, count how many decimal places are used by both numbers.

3) Place the decimal by counting back from the right the number of decimals places used in both numbers.


Examples and Practice

Dividing Decimals

Dividing by a whole number:

1) Use long division and ignore the decimal point. Line numbers up neatly where they belong during division.

2) Bring the decimal point straight up into your answer.


Dividing by a decimal number:

1) Multiply both numbers by a base 10 place value (10, 100, 1000 etc.) to shift the decimal out of the number that you are dividing by.

2) Divide the two new numbers.
