- What if there is no remainder for the whole number, Is this possible? .-.
Maybe with... 8/2 . How would I solve this into a mixed number?(36 votes)
- 3 4/4. 8/2=4 so 3 plus 4/4 also equals 4 because 4/4=1.(3 votes)

- Mathematics is very important in life, even if it doesn't seem like.
eg. Video games, food, transportations.
To think about it, almost everything includes mathematics.
For Mix Fraction in specific, they can be found a lot in cooking. You need it to measure how many cups of flour in your favourite cake, or how many cups of rice in your dinner.(22 votes)
- I have one question: sometimes you have to do these kind of things really fast; I was wondering if there was a fast and accurate way to convert fractions and mixed numbers, so you don't have to take that long and do all that stuff and take an hour to do one math problem.(11 votes)
- You can use Sal’s way of doing it, to get it faster, practice it multiple times.(4 votes)
- If there are mixed fractions and improper fractions I'm wondering if you can put a improper fration to a mixed fration and vis veversa(7 votes)
- Absolutely! For example, you can add 5/6 to 8/2 by making them common denominators (5/6+24/6 = 29/6) I hope this answers your question! :)(6 votes)

- what do you mean bruh its like if you have 7 rock's and you gotta get redov em all but too get redav em you have to find seven more rocks and ya find four ov em they cancel out four of the rocks you have 3 lef is basic subtract man I would not say this to ya face but sense ya probly won't see it anyhow If you dont no that well well well nevermind hope that help's cowboy(3 votes)

- What does the 7 in 7/4 mean?
Also what does the 4 in 7/4s mean?(4 votes)
- The 7 in seven fourths represents the amount you are counting. You're counting 4/4 and 3/4, so you're counting 7 of the fourths.
4 represents the amount in every whole.
If you divide two pizzas into four slices each and you eat one slice of one pizza, you have 7/4 slices left. Seven represents the amount you're counting, which is how much is left in this case, and four represents that there are four slices to a whole.(4 votes)
- how do you change fractions to improper fractions(3 votes)
- To change fractions (I assume you mean proper fractions) to improper fractions, take the whole number in the proper fraction and multiply it by the denominator of the fraction, then add that result to the numerator of the fraction and you will get the improper fraction. For example: 5 1/2 is the proper fraction. To convert it to an improper fraction multiply 5 by 2 which gives you 10. Then add 10 to the numerator which is 1. Your answer would end up being 11/2. I hope that helped.(5 votes)
Write 7/4 as a mixed number. So right now it's an improper fraction. 7 is larger than 4. Let's write it is a mixed number. So first I'm just going to show you a fairly straightforward way of doing it and then we're going to think a little bit about what it actually means. So to figure out what 7/4 represents as a mixed number, let me write it in different colors. So this is going to be equal to-- the easiest way I do it is you say, well, you divide 4 it 7. If we're dealing with fourths, 4 goes into 7 a total of one time. Let me do this in another color. 1 times 4 is 4. And then what is our remainder? 7 minus 4 is 3. So if we wanted to write this in plain-- well, let me just do the problem, and then we'll think about what it means in a second. So you see that 4 goes into 7 one time, so you have one whole here, and then how much do you have left over? Well, you have 3 left over, and that comes from right over there. That is the remainder when you divide 4 into 7. 3 left over, but it's 3 of your 4, or 3/4 left over. So that's the way we just converted it from an improper fraction to a mixed number. Now, it might seem a little bit like voodoo what I just did. I divided 4 into 7, it goes one time, and then the remainder is 3, so I got 1 and 3/4. But why does that make sense? Why does that actually makes sense? So let's draw fourths. Let's draw literally 7 fourths and maybe it'll become clear. So let's do a little square as a fourth. So let's say I have a square like that, and that is 1/4. Now, let's think about what seven of those mean, so let me copy and paste that. Copy and then paste it. So here I have 2 one-fourths, or you could see I have 2/4. Now I have 3 one-fourths. Now, I have 4 one-fourths. Now this is a whole, right? I have 4 one-fourths. This is a whole. So let me start on another whole. So now I have 5. Now I have 6 one-fourths, and now I have 7 one-fourths. Now, what does this look like? So all I did is I rewrote 7/4, or 7 one-fourths. I just kind of drew it for you. Now, what does this represent? Well, I have 4 fourths here, so this is 4/4. This right here is 3/4. Notice, 7/4 is 4/4 with 3/4 left over. So let me write it this way. 7/4 is 4/4 with 3/4 left over. Now what is 4/4? 4/4 is one whole. So you have one whole with 3/4 left over, so you end up with 1 and 3/4. So that is the 3/4 part and that is your one whole. Hopefully that makes sense and hopefully you understand why it connects. Because you say, well, how many wholes do you have? When you're dividing the 4 into the 7 and getting the one, you're essentially saying how many wholes? So the number of wholes, or you can imagine, the number of whole pies. And then how many pieces do we have left over? Well, we have 3 pieces and each piece is 1/4, so we have 3/4 left over. So we have one whole pie and three pieces, which are each a fourth left over.
