Working with Fractions Introduction to fractions Multiplication Addition Division Subtraction

Directions This program is to guide you to understand the basic of fractions. The mathematic operations (addition, subtraction, multiplication, and division) are explained. The examples will help you to drill in the basic principles. Make sure you know a section before you continue. The exercises will determine if you understood the section. When scoring 6 or more out of 8 you are ready to continue. The Clear button will reset the questions.

Introduction to Fractions If fractions are learnt well, they are fun and easy to do! So, spend some time on the following concepts. Fractions are expressed as one number over another number, like this: The number on the top is called the numerator and the number on the bottom is called the denominator. Numerator Denominator

Addition of Fractions 1/5 + 3/5 = 4/5 1 + 3 5 = To add two fractions together with the same denominator, add the numerators and place that sum over the common denominator. 1/5 + 3/5 = 4/5 1 + 3 5 =

Examples 1/5 3/5 = 4/5 + 6/4 5/4 = 11/4 + 2/6 1/6 = 3/6 + 1/9 6/9 = 7/9 +

Examples 1/2 5/8 = 9/8 + 1/4 3/8 = 5/8 1/3 5/6 = 7/6 + 1/2 1/4 = 3/4 +

Choose the Correct Answers 3/5 + 2/5 = 1/8 + 2/8 = 2/3 + 1/6 = 3/7 + 2/7 = 4/5 + 2/10 = 2/9 + 1/9 =

Subtraction of Fractions Fraction subtraction is similar to fraction addition. If the denominators are the same, subtract the second numerator from the first one. 5/8 - 1/8 = 4/8 5 - 1 8 =

Examples 11/3 4/3 = 7/3 - 3/7 1/7 = 2/7 - 8/13 2/13 = 6/13 - 6/9 4/9 = 2/9 -

Examples 1/2 1/4 = - 3/8 2/8 = 1/8 - 5/6 1/3 = 3/6 - 3/6 1/4 = 6/24 -

Fill in the Correct Fraction 2/2 - 1/2 = Possible answers 1/7 2/7 5/8 1/2 2/20 6/10 5/6 3/6 7/8 - 2/8 = 4/5 - 2/10 = 3/7 - 2/7 = 3/3 - 1/6 = 2/4 - 2/5 = 5/7 - 3/7 = 3/2 - 2/3 =

Multiplication of Fractions To multiply fractions, multiply the numerators together; and then multiply the denominators together. [The numerator is the number on top and the denominator is the number on the bottom.] 1/5 x 3/5 = 3/25 1 x 3 5 x 5 =

Examples 6/64 = x 3/8 2/8 1/8 = x 1/2 1/4 3/24 = x 3/8 1/4 5/18 = x 5/6 1/3

Exercise 3/5 x 2/5 = 1/8 x 2/3 = 7/5 x 2/4 = 3/7 x 2/1 5/4 x 3/2 Click on the drop-down and select the correct answer to these fractions. 1/8 x 2/3 = 7/5 x 2/4 = 3/7 x 2/1 5/4 x 3/2 2/1 x 2/1 3/2 x 7/3 2/4 x 1/6

Division of Fractions . 1/3 2/3 1/2 = x 2/1 To divide one fraction by another, turn the second fraction upside-down (invert it) and then multiply! 1/3 2/3 1/2 = . x 2/1

Choose the correct answer

Fill in the Correct Answers Possible answers 1/2 ÷ 1/4 = 1/2 x 4/1 = 10/10 15/10 12/14 8/16 4/2 4/3 9/3 40/20 1/2 ÷ 3/4 = 1/2 x 4/3 = 1/3 ÷ 1/9 = 1/5 ÷ 2/10 = 3/5 ÷ 2/5 = 4/5 ÷ 2/10 = 1/8 ÷ 2/8 = 3/7 ÷ 2/7 =
