Answer: Look at the variables (letters) and plug them in
Step-by-step explanation: You plug in the variables into the problem, then you separate the other variable that you don't know from your whole number by bringing it to the other side. Then you can divide or whatever you have to do.
9.0, or 9 IS a rational number.
A rational number is any number that could be expressed as a fraction. For example, the integers p/q as long as q is not equal to zero. 9.0 = 9/1; they are both natural numbers so 9.0 is rational. We can write that 10=101 .
To do this addition mentally, you should do like this:
31 requires 9 more to become 40 and since we have a nine in our question, we would first do 31 + 9 = 40. Now you would finish it off with the remaining number which is six. 40 + 6 = 46.
<u>Steps</u>:
31 + 9 = 40
40 + 6 =46
Therefore, your answer would 46.
