31/6 + 42/5 = 19/6 * 22/5 = 418/30 = 209/15 = 13.933...
2/15
It is 19/15 = 1 4/15.
two and two fifths
3/10
four fifth's times two is eight fifths (8/5) which is the same as one and three fifths (1 3/5)
Twenty four fifths is four and four fifths. So if you take three away, that leaves one and four fifths.
The answer is 5/6 times 6 and 4/5 = 5 and 2/3
52/5
Four fifths times 5 is 20 fifths which is equal to 4.
2 fourths times four fifths is 2 fifths.
4/5 x 1 1/6 is 14/15
4/5 x 1 1/6 is 14/15
