How do you put fractions into opposite fractions?
To put fractions into opposite fractions, all you have to do is flip it so that the numerator becomes the denominator and the denominator becomes the numerator. This is called a reciprocal. Example: The opposite of 3/5 is 5/3
All proper fractions with the denominator 3?
A proper fraction is a fraction where the numerator is less than the denominator. In this case, all proper fractions with a denominator of 3 would have a numerator less than 3. Therefore, the proper fractions with a denominator of 3 would be 1/3 and 2/3. These fractions represent parts of a whole divided into three equal parts.
What is simple form fraction?
SIMPLEST FORM fractions are fractions that have a denominator that is not divisible by the numerator 3/9 (pretend it is a fraction) can be simplified because both 3 and 9 are divisible by three, creating 1/3, which is in simplest form.
Why do fractions need to have a common denominator?
They need a common denominator when you add them. For example, if you want to add 1/2 and 1/3, you need to change the fractions to equivalents that share the same denominator, so you can combine them. 1/2 + 1/3 = 3/6 + 2/6 = 5/6
When you add or subtract fractions why doesn't the denominator change?
Because the denominator does not express a value, only the size of the parts being added or subtracted. You can think of integers as fractions with a denominator of 1. At any rate, 1/3 plus 1/3 = 2/3, as you can see with any sliced pizza. When you multiply fractions, the denominator is telling you to change the size of those parts, so that 1/2 of 1/3 is 1/6.
