Answer:


(149)/(40)


(38)/(15)

Explanation:


((7)/(8) + (4)/(5)) - ((9)/(20) + (-5)/(2)) =


= ((7)/(8) * (5)/(5) + (4)/(5) * (8)/(8)) - ((9)/(20) + (-5)/(2) * (10)/(10))


= ((35)/(40) + (32)/(40)) - ((9)/(20) + (-50)/(20))


= (67)/(40) - (-(41)/(20))


= (67)/(40) + (41)/(20) * (2)/(2)


= (67)/(40) + (82)/(40)


= (149)/(40)


(-(6)/(4) + (3)/(2)) + ((6)/(5) + (4)/(3)) =


= (-(3)/(2) + (3)/(2))+ ((6)/(5) * (3)/(3) + (4)/(3) * (5)/(5))


= 0 + (18)/(15) + (20)/(15)


= (38)/(15)
