Answer:
Rational
Step-by-step explanation:
A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever). However, one third can be express as 1 divided by 3, and since 1 and 3 are both integers, one third is a rational number.
The answer to this question is B.
So the first thing we need to do is set up an equation (using x to represent the number). Then, we'll solve it to get the answer.
Step 1: Translate the word problem into an equation
Word problem: The sum of nine and six-tenths and a number is thirteen and two-tenths.
Equation:
+ x = 
Step 2: Isolate x by subtracting
from each side
+ x -
=
- 
Step 3: The numbers on the left cancel out, leaving x alone
x = 
Step 4: Convert the answer to decimals
x = 3.6
