Question

(PLEASE HELP ME)

Which of the following equations is correct?

Please help me thank you so much!!

Answer 1

B

Explanation:

Distributive property: a*(b + c)= (a*b) + (a*c)

`(3)/(4)*((1)/(2)+(-2)/(5))=(3)/(4)*(1)/(2)+(3)/(4)*(-2)/(5)\\\\=(3)/(8)+(-6)/(20)\\\\=(3*5)/(8*5)+(-6*2)/(20*2)\\\\=(15)/(20)+(-12)/(40)\\\\=(15-12)/(40)\\\\=(3)/(40)`
