Answer:

Missing number = 68

Step-by-step explanation:

You can simply set up an equation like so: $x+(-56)=12$ .

Then, proceed to solve by isolating the x by itself.

x+(-56)=12

+56 +56 <--- Do the opposite operation on both sides to cancel the 56.

x=68

A quick pointer: A number plus a negative number is just subtracting so you can just work backwards.

Answer: 68.

What is a good comparison of the estimated sum and the actual sum of 7 9/12+2 11/12

earnstyle [38]

10 8/12 because you get an improper fraction when you add 9/12 and 11/12 (20/12) so you see how many times 12 goes into 20 which is only once. you see how many are left over from when you take 12 from 20. then you have you fraction which is 8/12. now you have to add the numbers which is 7+2=9 but 12 goes into 20 once so you add 1 to your number to make it 10. That's the answer, 10 8/12.
