What is 4/3 divided by 3/5

skelet666 [1.2K]

4/3 (which is 1 1/3 when you simplify it) divided by 3/5 is 2.216 with a vinculum on top of the six! An easier way to do this problem is to convert the fractions to decimals so the 4/3 would be 1.33 (with a vinculum) and 3/5 would be .60 and divide from there!
