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.

Let's try each of the choices:

A. The term 2/4 is a rational number. Now, when 0.3 or 3/10 is added to it, the sum would be 4/5 or 0.8. This is a rational number.

B. √7 is an irrational number because its exact value is 2.645751311.... Even if you add 0.3 to it, the answer would still be irrational

C. Obviously, this is an irrational number

D. The exact value of π is 3.14159...... If 0.3 is added to it, the answer would be 3.441592654. This is irrational.

Therefore, the answer is A.

Simplify: 10 • 12 + - 15 divided by 5 + 2 (9-4)

Alright. So the problem is

10*12+-15/5+2(9-4)

Lets break down what we can for now

First focus on parenthesized, multiplying, and dividing in the problem.

10*12=120 15/5=3 (9-4)=5

120+-3+2*5

So the next step, we see 2*5 and a negative -3 on top of a positive symbol.

2*5=10

120-3+10

Now subtract from the left to the right and get your answer.

120-3=117

117+10=127
