Half of a Half<\/strong><\/h2>\n\n\n\n

Here is a picture of a pizza. This picture shows a whole pizza. The whole pizza is 100% of a pizza.<\/strong><\/p>\n\n\n

\n
\"a<\/figure>\n<\/div>\n\n\n

If someone ate half of the pizza, then half of the pizza would be left. Half of the pizza is 50% of the pizza.<\/strong><\/p>\n\n\n

\n
\"Half<\/figure>\n<\/div>\n\n\n

What do you think would be left if someone ate half of the half pizza above? What fraction of a pizza would that be? What percent of a pizza would that be? Before you keep reading, try drawing a picture of what you think this might look like<\/strong>. <\/p>\n\n\n\n

<\/div>\n\n\n\n

Ready to see a picture?<\/strong><\/p>\n\n\n\n

<\/div>\n\n\n\n

Here is a picture of what it might look like if someone ate half of the pizza that was left. Can you see what fraction of a pizza it is? Can you see what percent it is? (If you’re not sure, keep reading!)<\/p>\n\n\n

\n
\"a<\/figure>\n<\/div>\n\n\n

Here is another picture of the same part of the pizza, but with some extra lines drawn in to help you see the fraction.<\/p>\n\n\n

\n
\"a<\/figure>\n<\/div>\n\n\n

This picture shows that the part of the pizza that is left is one out of four equal pieces. As a fraction, that is called one-fourth. It also is sometimes called one quarter.\u200b<\/p>\n\n\n\n

As a fraction, one-fourth looks like this: <\/p>\n<\/div>\n\n\n\n

\n
\"\u00bc\"<\/figure>\n<\/div>\n<\/div>\n\n\n\n

It can also be written as 1\/4<\/strong>.<\/p>\n\n\n\n

Because 1\/4 is half of a half, the percent for 1\/4 is half of 50%. Half of 50% is 25% so 1\/4 means the same thing as 25%.<\/strong><\/p>\n\n\n\n

Just like there are many ways to write the fraction 1\/2, there are many ways to write the fraction 1\/4. The interactive model below shows a rectangle that has 1\/4 or 25% colored orange. You can tell that it is 1\/4 because it is 1 of 4 pieces that are all the same size. You can drag the orange dot to find some other ways of saying 1\/4. Play with it and see if you can find a pattern<\/strong>. Don’t forget that the numbers in the boxes show you the sizes of the boxes and that you can also look at the number line to see parts and wholes!<\/p>\n\n\n\n
