Answer:
A is the answer.
Step-by-step explanation:
A fraction plus a fraction is equal to a fraction. An irrational number cannot be expressed as a fraction.
0.3333333 even though it looks like an irrational number it is actually: 1/3
3/5 is already a fraction so adding it with another fraction will NOT equal an irrational number (decimal)
-0.75 is equal to -3/4 (75/100 => 3/4). Same thing that applies above.
However, Pi cannot be expressed as a fraction exactly. You can round up like 3.14. However it is not the full number. So 3.141592654....+(3/4) is not going to add up perfectly into a fraction.
In short, a fraction is a rational number. Rational + Rational = Rational. Irrational + Rational = Irrational.
Answer:
<em>D. 3.5!</em>
Step-by-step explanation:
If you slowly go up the line it will be 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, if it were to carry on it would keep being .5 then the next number. Since this is not a fraction number line the answer is not A. -9/2 nor C. -7/2.
