An improper fraction is one in which the numerator is larger than the denominator, as a result of which the value of the fraction is greater than one, and it could be expressed therefore as some integer plus a proper fraction in which the numerator is smaller than the denominator.

When the numerator is equal to the denominator it equals 1 if the numerator is greater than the denominator then you could change it to a mixed number like 3/2 equals 1 1/2

As the numerator and denominator don't have any common factors then the fraction is in its simplest form. If they weren't relatively prime then there would be a common factor and therefore the fraction could be simplified.

If the denominator is more than double the numerator, then the fraction is less than a half.

Yes. for example, if the fraction is 4/10 you could divide both the numerator and the denominator by 2 and that would simplify to 2/5. you just have to make sure that you do the same thing to the numerator that you do to the denominator, so you can't divide the numerator by 2 and the denominator by 5.

yes it could be

The denominator must be double the numerator.

Any question that has a numerator and a denominator is a fraction. Therefore, the answer could be 63/1, 63/2, 63/3, etc.

It could be simplifying the fraction.

An improper fraction is a fraction where the numerator (top number) is greater than the denominator (bottom number), and therefore could be written as a mixed number. For example, 7/6 could be written as 11/6. Improper fractions are useful in many mathematical operations.

An example would be: 14 over 8. That could be converted into 1 and 6 over 8, which you can simplify into 1 and 3 over 4.

If a fraction is equivalent to one-half then the numerator is always half the denominator. Or, the double the numerator is the denominator. So, given any other fraction, p/q, if 2p < q then the fraction < 1/2 if 2p = q then the fraction = 1/2 if 2p > q then the fraction > 1/2

An equivalent fraction to 5/12 could be 10/24 by multiplying the denominator and the numerator by 2.

The same way as multiplying a whole number by an ordinary fraction: Multiply the numerator (top number) by the whole number and put it over the original denominator (bottom number). This can then be simplified by dividing the numerator and denominator by their highest common factor; or it can be converted into a decimal (which could be a whole number) by dividing the numerator by the denominator.

This could be any fraction where the denominator and the numerator are different. For example, 1/2, 3/7, 15/8......and so on. In algebraic terms this would be written x/y where x ≠ y

I think you round the numberator to the nearest number it could be divided into and go from there.

I am pretty sure its the numerator, but it could be the denominator.

It's the denominator I think, but it could be the numerator

Here is an example. The fraction to simplify is 6/12. See if there is a common factor between the numerator and the denominator. In this case, 3 happens to be a common factor. Divide numerator and denominator by 3. The result is 2/4. See if there are more common factors, and repeat. Dividing numerator and denominator by 2, you get 1/2. You could also have divided numerator and denominator of the original fraction by 6, with the same final result - but sometimes it is easier to do it in parts.

A fraction is in its simplest form if its denominator (bottom half of the fraction) and numerator (top half of the fraction) cannot be divided by the same number to equal a fraction with whole numbers in the numerator and denominator. [When you 'cancel' a fraction out (divide it to get a smaller fraction, closer to the simplest form) you must do the same sum to the numerator AND the denominator, so you must be able to divide the numerator by the same number you divide the numerator by, as the fraction cannot contain decimals or remainders (it must be a whole number] e.g. 3/6 is NOT in its simplest form, as you can divide both numbers by 3, meaning that the simplest form would be 1/3 1/3 is in its simplest form, as although you could divide the denominator by 3, you cannot divide the numerator by 3 to equal a whole number.

Improper could refer to a fraction such as, 27 over 9. the denominator is less than the numerator.

The original fraction is -145/(-282) or it could be 850/35700 or one of infinitely many possibilities.

You could leave it as an improper fraction. Alternatively, you could divide the numerator by the denominator (d) to find the number of times it goes into it (w) and the remainder (r). Then the equivalent mixed ratio is w r/d.

Fractions have numerators and denominators. 81 isn't a fraction. You could write it as "81/1" if you want to. Then the numerator is 81, and the denominator is 1.

If the GCF of the numerator and denominator is 1, the fraction is in its simplest form.
