Question

show that :(-2/3-(4/-5))-1/2=-11/30​

Answer 1

Step-by-step explanation:

First let us see inside the bracket.

-2/3 - ( 4/-5 )

= -2/3 + 4/5                                      <LCM of 3 and 5 is 15, but making the

= -20/30 + 24/30                               denominator 30 will make it easier

=  4/30                                                later>

Now let us solve the rest

 [ -2/3 - ( 4/-5 ) ] - 1/2

= 4/30 - 1/2

= 4/30 - 15/30

= -11/30
