Four divided by one and one fourth = 16/5 or 31/5
To add one fourth and four fifths, first find a common denominator, which is 20. Convert one fourth to 5/20 and four fifths to 16/20. Adding these together gives you 5/20 + 16/20 = 21/20, which can also be expressed as 1 and 1/20.
The answer is 1

1.5
It is: 2.25/5.4 = 5/12
