Answer:


(9)/(16)*(4)/(12)+(9)/(16)*-(5)/(9) = -(1)/(8)

Step-by-step explanation:

Given


(9)/(16)*(4)/(12)+(9)/(16)*-(5)/(9)

Required

Solve


(9)/(16)*(4)/(12)+(9)/(16)*-(5)/(9)

Apply distributive property


(9)/(16)*(4)/(12)+(9)/(16)*-(5)/(9) = (9)/(16)((4)/(12)-(5)/(9))

Solve the bracket


(9)/(16)*(4)/(12)+(9)/(16)*-(5)/(9) = (9)/(16)((12 - 20)/(36))


(9)/(16)*(4)/(12)+(9)/(16)*-(5)/(9) = (9)/(16)((-8)/(36))\\

Simplify


(9)/(16)*(4)/(12)+(9)/(16)*-(5)/(9) = (9)/(16)((-2)/(9))

Open bracket


(9)/(16)*(4)/(12)+(9)/(16)*-(5)/(9) = (1)/(16) * (-2)/(1)


(9)/(16)*(4)/(12)+(9)/(16)*-(5)/(9) = -(2)/(16)


(9)/(16)*(4)/(12)+(9)/(16)*-(5)/(9) = -(1)/(8)
