Introducing: fraction form mixed form Mixed Form To Fraction Form

This picture shows the fraction 1. The complete circle on the left is selected and of the other circle is selected. A fraction such as 1 that has a whole number part and a fraction part is a mixed number. Mixed Form To Fraction Form

Every whole number or mixed number can be written in fraction ( ) form. abab

What does that mean? Every whole number or mixed number can be written in fraction ( ) form. abab

Each circle is divided into three parts. Each part is Add up all of the shaded parts and you get. Count them and see Look at the circles below … 1313

5353 The fraction form for 1 is

You can calculate the fraction form for 1 by multiplying the whole number 1 by the denominator 3 and then adding the numerator 2 for a numerator of 5 in the fraction form How to calculate fraction form

Of course, you can look at the picture to see that there are 5 one-third units or. Also, you can think of the unit 1 as. Add to the partial unit for the fraction form. This picture shows that 1 = + =. Mixed Form To Fraction Form

MIXED FORM TO FRACTION FORM- AN EXAMPLE

Elu and Lallo made 7 pies, each with 4 pieces for the 11 people in their family. On their way home, Elu and Lallo got hungry and ate 5 whole pies plus two extra pieces from another whole pie. Is there enough pieces to feed each member of their family?

So Elu and Lallo ate 5 whole pies and 2 slices from one whole pie:

Now to rewrite that as a fraction: 5x4+2 4 = 22 4

Because they bought 7 pies with 4 pieces, it can be written in fraction form as: 7x4+0 4 = 28 4

We can go ahead and compare both fractions now: So out of the 28 pieces, there was only 6 pieces left and because they have 11 people in their family, there is not enough pie for everyone = 6464
