Hi,

1) the choices it self give you the answer straight way..
In ((-1.9)(0.6) – (2.6)(1.2))/6.0 , the NUMERATOR, ((-1.9)(0.6) – (2.6)(1.2)), is addition of two -IVE terms, so N is -ive..
6, the DENOMINATOR, is positive..
-ive term/ +ive term will alwys be -ive..
Only A fits in..
ans A

2) ((-1.9)(0.6) – (2.6)(1.2))/6
Take out 6 as common term
= 6(-1.9*0.1-2.6*0.2)/6= (-.19-.52)
=> -.71
A

Dove straight into calculation but quickly realized that the sum of two negatives is a negative so there is only one option.
