Hi!
Let's convert this mixed number to an improper fraction.
To convert numbers to improper fractions, we multiply the denominator by the whole number, then add that to the numerator. That becomes the new numerator.
4 · 11 = 44
44 + 3 = 47

Now we can divide the numerator by the denominator to find the decimal!
47/11 = 4.27
The answer is 4.27Hope this helps! :)
