Answer:

a)
(11)/(15)

b)
(1)/(18)

Explanation:


a) \: (2)/(5) + (1)/(3)


(2)/(5) * (3)/(3) + (1)/(3) * (5)/(5)


(2 * 3)/(5 * 3) + (1 * 5)/(3 * 5)


(6)/(15) + (5)/(15)


(6 + 5)/(15)


(11)/(15)


b) \: (5)/(9) - (1)/(2)


(5)/(9) * (2)/(3) - (1)/(2) * (9)/(9)


(5 * 2)/(9 * 2) - (1 * 9)/(2 * 9)


(10)/(18) - (9)/(18)


(10 - 9)/(18)


(1)/(18)

Hope it is helpful...
