- I don't understand, they were separate shapes so shouldn't the first one have been 2/3 and the last one be 3/3? Why put them together if they are separate?(61 votes)
- We are looking at how many pieces of the whole. One circle is a whole. (We find it helpful to say one whole pizza). If we ate two slices and ate three slices, we ate 5/3 or 5 thirds. One whole is still only one pizza no matter how many slices we eat. We want to know what fraction we ate, so we count up all the shaded slices.(28 votes)

- At0:58, shouldn't the two circles (each having three parts) add up to six parts? Shouldn't the answer be 5/6 as opposed to 5/3?(9 votes)
- The denominator of a fraction
**always**tells you the number of parts that will**create 1 whole unit**.

Each circle is a single unit. To make up one circle (or one unit) it take 3 parts.

If you have 5/6, you are saying that 5 parts of an object that has been split into 6 parts. Or, one circle split into 6 parts with 5 shaded.

- Can fractions be represented in a decimal form?(20 votes)
- Yes, fractions can be converted to decimals.

For example: To, change 3/4 into a decimal you would 3 by 4. This will create 0.75

- This was obviously confusing to me. I totally did not get how that was showing a fraction greater than one. I mean, to me it looked like 2/3 and 3/3. Why couldent you just simply add the numerators?(8 votes)
- You could just add the numerators, which gets you 5/3.

But, you need to recognize that it is an improper fraction and that it is larger than 1 which is what this video is trying to show you.

5/3 = 1 2/3 (one whole unit and 2/3 of another unit).(10 votes)

- when I have a number like this 5/5 that means one why? and why cant it mean two(5 votes)
- because if you had one shape then you divided it into fifths you still have one shape. if you colored 5 of the 5 sections then you don't suddenly have two shapes appear that are all shaded in.(3 votes)

- what happens if parts of a fraction arnt equal(3 votes)
- Fractions by definition have parts that are equal. When you get to adding fractions, you will learn how to take fractions with different denominators (different sized pieces) and create equivalent fractions so the parts become equal.(3 votes)

- where is sal? i want to see him/////(3 votes)
- sorry but for real i don't understand anything(1 vote)
- Its ok you can improve in the future.(3 votes)

- Why didn't the question say in both shapes because they are two different shapes not one big shpe.(2 votes)
- one more time

## Video transcript

- [Voiceover] This circle
represents one whole. This circle right here
represents one whole. If we know that, we can
answer what fraction of the circle is shaded in blue below? So down here. What fraction is in blue? Let's start back up here with the whole. This whole is divided into one, two, three equal size pieces, so
it's divided into thirds, three equal size pieces. And each of those pieces,
each of those pie pieces, is 1/3, is one of the thirds. So knowing that, let's go
down here to these ones and lets see how many of these 1/3 pieces. Here's 1/3, another 1/3,
another 1/3 shaded in blue, another one and another one. So we have one, two,
three, four, five thirds. We have 5/3 shaded in blue below.
