Question

is this associative -2/3+[3/5+(-5/6)]=[-2/3+3/5]+(-5/6)​

Answer 1

Answer:

-2/3+[3/5+(-5/6)]=[-2/3+3/5]+(-5/6)

so -2/3+[18/30-25/30]=[-10/15+9/15]-5/6 after taking lcm of denominators and equating the numerator.

-2/3+(-7/30)=(-1/15-5/6)

-27/30= -27/30

hence the equation is associative
