how do you write
5 and a half in a fraction not like this because i thought it was
5 1/2 but it was wrong.
5 1/2 is also 11/2, which is considered an improper fraction.
I hope this is what you were asking.
To write 5 and a half (5 1/2) as a fraction, you did it correctly. However, if you are looking for an alternative form that is not considered an improper fraction, you can express it as a mixed number.
A mixed number represents a whole number combined with a fraction. To convert an improper fraction, such as 11/2, into a mixed number, you divide the numerator (the top number) by the denominator (the bottom number). The quotient becomes the whole number part, and the remainder becomes the new numerator.
For example:
11 ÷ 2 = 5 with a remainder of 1
So, the mixed number form of 11/2 is 5 1/2, which is equivalent to 5.5.
Therefore, 5 and a half can be written as either 5 1/2 or 5.5. Both represent the same value in different formats.
