espero que sea lo que necesitas.

Answer 2

a) 5 - (1/4 + 5/2) =  5 - (1+10)/4 = 5-11/4 = (20-11)/4 = 9/4

b) 3/7 + (2/5 - 1) = 3/7 + (2-5)/5 = 3/7 - 3/5 = (15-21)/35 = -6/35

c) 5/7 · (1/3 + 2/15) = 5/7 · (5+2)/15 =  5/7 · 7/15 = 5*7/(7*15) = 
                                = 5/15 = 1/3

d) 1/4 – 5/6 : 2/9 = 1/4 - (5/6 * 9/2) = 1/4 - (5*9/6*2) = 1/4 - (5*3/2*2) = 1/4 - 15/4
                           = (1-15)/4 = -14/4 = -7/2
