when adding two rational numbers tell what the sign of the sum will be if one rational number is positive and one is negative

It will be negative

Step-by-step explanation:

For example 2+(-5)= would equal -3 because if you plot it on a number line and go 2 spaces up but then go down -5 times you will land on -3.

Hope this helps :)

because 1.2 isnt half of 6 duh
