Answer is 20.

The smallest fraction is the fraction with the smallest numerator and the largest denominator. The smallest number from 3, 4 and 5 is 3. The largest number from 3, 4 and 5 is 5. The smallest fraction is 3/5

15 is the smallest number divisible by both 3 and 5

5. To leave a remainder of 1 when divided by 2, the number must be odd. To leave a remainder of 2 when divided by 3, the number must also be two more than a multiple of 3. The multiples of 3 which are odd are 1 x 3, 3 x 3, 5 x 3, etc. The smallest odd multiple of three is 1 x 3 = 3 ⇒ required number is 3 + 2 = 5.
