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?(37 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.(18 votes)
can fractions represented in a decimal form(18 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

If there was was two pizzas, why would the denominator still be the same sometimes? (I said sometimes)(11 votes)- If you slice up a pizza into eight slices, and eat one slice, you have eaten 1/8 of the pizza. If you eat another piece, you will have eaten 2/8 of the pizza.
If you slice up two pizzas, you will have sixteen slices. Eat one slice and you will have eaten 1/16 of the two pizzas. If you eat another slice, you will have eaten 2/16 of the two pizzas.
I hope this helps you understand how the denominator can remain the same.(6 votes)
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?(6 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).(9 votes)
how am i supposed to recognizied fractions that are greater then 1?(7 votes)
Well 5/3 would be 3 equal pieces with 5 of them shaded in but you would need like, 2 pies with three slices and someone ate 5 of the three slices, I know that would kinda sound like 5/6 but it's not it's 5/3 so that means the person a 5 slices of two pies with 3 pices.(5 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.(4 votes)
Are there Spanish tutorial videos on fractions greater than 1 for third grade?(3 votes)
I recommend you to use the captions as well. I speak native Portuguese but I'm watching every video in english with captions, think of that as learning 2 things at the same time, MATH and English :)(8 votes)
- Im so bad at fractions Im SO HAPPY MY TEACHER IS TEACHING ME FRACTIONS(5 votes)
i don't know what to write when it says What part of the square is shaded.(4 votes)
lets say you have 1 half of a candy bar you would rite it like 1/2. or you have 3/3 of crowns that means you have a whole box but you only get 1 quarter of a box. so you get 1/3 of a box of crowns. hope this is what you asked.(4 votes)
- I get it and then I dont.please be a little more spcific(4 votes)

- [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.
