To add fractions you can use many examples to show it. Some of these exampels are clocks, money, and a double numberline. =CLOCKS: 1/5 + 3/4= Step One - First make a circle and divide it out of 5 because the denominator is 5. Then you will divide 5 by 60 because all clocks are out of 60 minutes.

Step Two: Now that you have done the first fraction you rpeat the same steps as before. When you get your final number you add them together and make the denominator out of 60 minutes.

=MONEY: 1/5 + 3/4= I am going to use the same question becasue it will give you a better understanding of some of these examples. Step One - You want to divide the denominators by the whole which is 100 because money is always out of 100.



Once you divide each of the denominators for both fractions you then multiply your answer by the numerator. Then you add it together and make sure your ending fraction is out of one hundred. Also make sure to simplify your answer!

=DOUBLE NUMBERLINE: 2/4 +1/6= When using a numberline you can make it out of any number that both the denominators are divisible by. Since both of our denominators are 4 and 6 they are both divisible by 24.

Since we made our timeline out of 24 you need to divide each denominator by 24 to get a fraction. Remember to simplify your answer as your final product.

=SUBTRACTING FRACTIONS:=

For subtracting fractions you can use clocks, money, and a double numberline as examples. =Money: 3/5 - 1/4=

Step One: Repeat the same steps as before when adding fractions, but this time you only subtract.

=CLOCKS: 3/5 - 1/4=

Remember that clocks are stil out of 60 minutes.

=DOUBLE NUMBERLINE: 3/5 - 1/4= As you can see we are using the same examples again to give you a better understanding about how to use them on different fractions.

As you can see making a number line is very simple to do. We chose the number 60 because both denominators are divisible by it.

1/4 = 15 3/5 = 15 The nyou subtract that to get your answer of 21/60.

=DIVIDING FRACTIONS:=



A easy and simple way of showing how to divide fractions is using a t-chart. Remember what you do to one side you do to the other.You want to make the fraction improper because it is easier to get to the whole. =MULTIPLYING FRACTIONS:=

=MIXED FRACTIONS:=

To multiply mixed fractions you first multiply the denimnators together. Once you have done that the nyou multiply the numerators together. Now multiply the wholes together and then simplify your answer. =MULTIPLYING FRACTIONS:=

To multiply regular fractions all you need to do is muliply the numerators together and then the denominators together. Once you have done that just simplify answer if needed. =ARRAY MODELS=



When using array models it is easier than it looks!

First you draw a box and the nyou use the denominator as rows and column amounts. Next you shade in 3 going down one column. We use 3 because it is the numerator and 1 because that is the numerator of the other fraction.
