To estimate the sum or difference of 8/9 + 4/7 it should be <span>1 1/2
</span>It is also a way to find<span> an approximate answer to a solution. To </span>estimate<span> products and quotients of mixed numbers, round the </span>fractions<span> to the nearest whole number. If the </span>fraction<span> is less than 12 round down and if it is more than 12 round up. First, since 411 is less than 12,8411 rounds down to 8.</span><span>

Answer:
-12 47/60
Step-by-step explanation:
-(1 1/5) + (-8 3/4 -2 5/6) = -(1 + 8 + 2 + 1/5 + 3/4 + 5/6)
= -(11 + 12/60 +45/60 +50/60) . . . 60 is the LCD of 1/5, 3/4, 5/6
= -(11 + 107/60) . . . . . . . . . . . . . . . . add the fractions
= -(12 47/60) = -12 47/60 . . . . . . . write as a mixed number

Your graphing calculator may be able to do this for you. Many handle mixed numbers with ease.
Answer:
1) -12 + 5 = -7 you just set it up and solve it like a regular problem and then to see if its a - or + we see what number was bigger so -12 is bigger then +5 so our answer is -7
2) 7 -3 + 15 - 2 - 3 + 6 so lets add up all the negative numbers and all the positive numbers so now we have + 28 - 8 so the we solve +28 - 8 = +20 again the sign goes with the bigger number!
Hope this helps!!! Good luck!!! ;)
