12+2= 14
4+7=11
-9+3=-6
-14 +5 = -9
-11+ -2 = -13
-3+ -8 = - 11

Answer:
Step-by-step explanation:
cute it into separate parts then add the areas together
It cant be converted into a mixed number because it has no whole.
To answer this we will add, but before we add we will change 4/5 in to a decimal. to change ANY fraction into a decimal we have to divide the numerator by the denominator. lets do it:-
4/5
4 ÷ 5 = 0.8
Now lets substitute 0.8 for 4/5 and then add.
4/5 + 0.05
0.8 + 0.05 = 0.85
CHECK OUR WORK:-
0.85 - 0.8 = 0.05
We were RIGHT!!
So, the decimal 0.85 is equivalent to 4/5 + 0.05.
Hope I helped ya!! xD
