Answer:
Completing the square. I mean, you can, for some values of a and b, but it's not going to help much if it is messy. Nope!
Factoring. Yes. It's really easy since there is an obvious common factor.
Square root theorem. No idea what this is. And I don't know how it would help.
Quadratic equation. This works, but is a little long for what you have to do.\
67.8: 6.78, 0.678, 0.0677
456.8: 45.68, 4.568, 0.4568
531.20: 53.12, 5.312, 0.5312
The pattern here is that the number of 0s there are in the digit of whatever you are dividing by, that is how many places you move the decimal place to the right. For example, by dividing 67.8 by 100, the decimal place has been moved 2 places to the right, resulting in the number 0.678
It would be 59 if you are rounding to the one's nearest whole's number.

Answer:
8/3 is between 2 and 3 above 2.5
11.3 is between 3 and 4 above 3.5
Step-by-step explanation:
8/3 converts to the decimal 2.666666... which means its located on the number line between 2 and 3 above 2.5.
11/3 converts to 3.6666.... which means its located on the number line between 3 and 4 above 3.5.
