okay so 11.8 as a improper fraction is
59
---
5
but we want that as a mixed number so how many times does 5 go into 59? 11 times right. soooooo, so far our whole number is 11...... but 5 times 11 is 55 so how many remain? well
59 - 55 = 4 so lets write out our fraction
4
11 ---- or 4/5 could be also 8/10s its just simplified
5
the bottom number stays the same!
hope this helps explain more clearly:)
Both 11 and 4/5 or 11 and 8/10 are correct answers:)
