To convert the improper fraction 18/5 into a mixed number, we need to divide the numerator by the denominator.
When we divide 18 by 5, we get 3 with a remainder of 3. This is because 5 goes into 18 three times (5 x 3 = 15), and when we subtract 15 from 18, we have 3 left over.
Therefore, we can express this as a mixed number:
The whole number part is 3, and the fractional part is the remainder (3) over the original denominator (5). So, we write it as:
3 3/5
In summary, 18 5 as a mixed number is 3 3/5.
