I think you are asking for two numbers, so you just have to look at the decimals.
23.7
We can use an infinite amount of numbers here, but to make it simple you can just take away 0.01 or add 0.01.
23.69
23.71
These are funny answers as well because they both round to 23.7 and meet the requirements.
Do you have a specific equation I can help you with. I can explain them better with a problem to look at?
If you know the formular a^3+b^3=(a+b)(a^2-ab+b^2), you can solve this problem.
8 is 2 cubed, so x^3+2^3=(x+2)(x^2-2x+4)
so the other quadratic factor is x^2-2x+4

3/4 is the highest fraction of the four options.
