<h3>How to identify rational numbers?</h3>
A rational number is an algebraic term expressed as a fraction. The fraction can also be in decimals but only if the decimal places are not repeating or not infinitely long. If they aren't, then these are called irrational numbers.
Now, let us convert 0.85 to a fraction. Thus;
0.85 = 85/100 = 17/20
From the given options, the only one that when added to 0.85 will yield a rational number is 2/9. This is because;
17/20 + 2/9 = 193/180
193/180 is a rational number.
The missing options are;
A. 2/9
B. 0.2645751311...
C. √2
D.

Simple it says you use 33 drops of yellow originally and 44 drops of blue it appears that each drops are 11 drops lesser (from blue to yellow). Therefore, add 11 to 1212 and you get your answer.
You would divide 76 by 8. That would give you 9.5. Then you multiply by 10 and that gives you 95. Hope this helps (;
