1) (a+b)+c
(-2+ -2/3) + -3/4
=(-2/1 - 2/3) - 3/4
BODMAS
B for Brackets first
Finding the LCM,
= (-6/3 -2/3) - 3/4
= (-8/3) - 3/4
=-8/3 - 3/4
LCM again,
= -32/12 -9/12
=-41/12
2) a+(b+c)
-2+ (-2/3 + -3/4)
= -2/1 + (-2/3 - 3/4)
BODMAS
B for Brackets first
Finding the LCM,
= -2/1 + (-8/12 - 9/12)
= -2/1 + ( -17/12)
= -2/1 -17/12
LCM again,
= -24/12 - 17/12
=41/12
