Question

-1+(2/3+-3/4)=(-1+-2/3)+-3/4.

Answer 1

-1+(8-9/12)=(-5/3)-3/4

-1-(1/12)= -20-9/12

-13/12= -29/12

-13+29/12

= 16/12=4/3.

Thank You!!☺️

Have a nice evening.

Answer 2

Hii friend,

-1 + (2/3 + (-3/4) = (-1 + (-2/3) + (-3/4)

=> -1 + (2/3 - 3/4) = (-1 - 2/3) - 3/4

=> -1 + ( 2 × 4 - 3 × 3 ÷ 12) = (-1 × 3 - 2 × 1 ÷3) -3/4

=> -1 + (8-9/12) = (-3 -2/3) -3/4

=> -1 + (-1/12) = (-5/3) - 3/4

=> -1 - 1/12 = -5/3 - 3/4

=> -1 × 12 - 1 × 1 ÷ 12 = -5 × 4 - 3 × 4 ÷ 12

=> -12 -1/12 = -20 - 12 ÷ 12

=> -13/12 = -32/12

=> -13 × 12 = -32 × 12

=> -156 = -384

=> -156 + 384

=> 228 ...Ans.


HOPE IT WILL HELP YOU..... :-)
