- How do you find a opposite from a fraction?(32 votes)
- There are negative fractions; these are the opposites of positive fractions. If you had 3/4 for instance, it's opposite is -3/4. There is also something else you can sorta classify as a opposite of a fraction-- its reciprocal. A reciprocal is just the fraction turned upside down; the reciprocal of 3/4 is 4/3.

- So basically whatever the positive number is, the opposite would be the same digit but with a negative at the front?(18 votes)
- Yes a positive number with a negative in front of it.(11 votes)
- what is the opposite of -20(8 votes)
- 20 because it's the same distance from zero as -20(15 votes)
- Here's a hard one:
- If the signs are the same, you add and keep the sign, and if they are different you subtract and keep the sign of the larger number. So -3+-4 is -7(6 votes)
- How do you find the opposite of a fraction?(6 votes)
- To find the opposite of a fraction you just do the same thing you would do with a whole number. If you need to find the opposite of -4 1/2 , you can find the opposite of -4, Which is 4, then add the 1/2.(10 votes)
- I heard about the function
absolute valueand I did not understand what it meant.
could anybody explain please?(6 votes)
- The number's value from zero. For example, if you are standing on a starting line and walk backwards 7 meters you could say you went -7 meters distance (in other words you would have to go 7 meters just to get back to zero, or the starting line). However, the absolute value of how far you have walked would be 7 meters, not -7. In essence, it removes the negative from negative numbers, giving only their value (so -7 becomes 7, -215 becomes 215, etc.)(9 votes)

- if the opposite of a number is the number the same distance from 0 what is the opposite.(7 votes)
- It is the same number, just it is a negative instead. If it is already a negative, than it is the same number but a positive instead.(6 votes)
- what's the opposite of 0? it's just 0 lol. Is zero positive or negative? PLease answer, buddies!(5 votes)
- Zero is neither. It's like how 1 isn't a composite or prime number. It's neither! Good question!❤❤❤(5 votes)

- It is neither positive nor negative, it is the only neutral number.(5 votes)
- [Voiceover] What I want to do in this video is think about what it means to have an opposite of a number. Let me draw a number line here. Let's draw a number line. And let's put some numbers on this number line. We can start at zero, and if we go to the right we have positive numbers. One, two, three, four, five. As we go to the left we get more and more negative. So negative one, negative two, negative three, negative four, and I can keep going on and on and on. Let's pick one of these numbers. Let's say that we pick the number three. What is going to be the opposite of the number three? Well the opposite of the number is a number that's the same distance from zero but on the other side. So three is three to the right of zero. One, two, three. So its opposite is going to be three to the left of zero. One, two, three. So the opposite of three is negative three. Let me make a little table here. If we have the number, the number. And then we have its opposite. We have its opposite. So we just figured out that if you have the number three, its opposite is going to be negative three. Now what if your number is negative? What if your number, let's say the number negative four. What's the opposite of that? And I encourage you to pause the video and try to think about it on your own. Well, you say, okay, negative four is right over here. That's negative four. It is four to the left of zero. One, two, three, four to the left of zero. So its opposite is going to be four to the right of it. So one, two, three, four. It's going to be positive. It's going to be positive four. So you're probably starting to see a pattern here. The opposite of a number is going to be the opposite sign of that number. If you have a positive three here, its opposite is going to be negative three. If you start with negative four, its opposite is going to be positive four. One way to think about it, it's going to have the same absolute value but have a different sign. Or another way to think about it is, however if this is three to the right of zero, its opposite is going to be three to the left of zero. Or if the number is four to the left of zero, its opposite is going to be four to the right of zero. So we'll do one last one. What is the opposite of... What's going to be the opposite of one? Well one is one to the right of zero, so its opposite is going to be one to the left of zero, or negative one. Or another way to think about it, one is positive so its opposite is where you're going to change the sign. Instead of being positive it's going to be negative. It's going to be negative one. Either way that you can think about it.
