To add these fractions, we first need to find a common denominator. In this case, the common denominator is 10 (because 10 is the smallest number that 2, 5, and 10 all divide evenly into).
-7/10 + (-1/2) + (-4/5)= -35/50 + (-25/50) + (-40/50) (find equivalent fractions with denominator 50)= (-35 - 25 - 40) / 50= -100 / 50= -2
Therefore, -7/10 + (-1/2) + (-4/5) = -2.

= -35/50 + (-25/50) + (-40/50) (find equivalent fractions with denominator 50)
= (-35 - 25 - 40) / 50
= -100 / 50
= -2
Therefore, -7/10 + (-1/2) + (-4/5) = -2.
