ANSWER
-5 is a real number, a rational number, and an integer

EXPLANATION
Rational number are numbers which you can write as a quotient of two integers. Integers are non-decimal numbers that can be positive or negative. We can therefore write -5 as -5 divided by 1 (-5/1) and thus classify -5 as rational.

In fact, you can classify -5 into other categories.

-5 is all of the following
⇒ it is a real number
⇒ it is a rational number
⇒ it is an integer

Whole numbers can be considered as {0, 1, 2, 3, ...}
Natural numbers can be considered as {1,2,3,...}

so -5 is not a whole or natural number.

\boxed{ \begin{array}{l r} \textbf{real numbers } (\mathbb{R}) \\ \boxed{ \begin{array}{l} \textbf{rational numbers } (\mathbb{Q}) \\ \boxed{ \begin{array}{l} \textbf{integers } (\mathbb{Z})\\ \boxed{ \begin{array}{l} \text{\footnotesize whole numbers ($\mathbb{W}$)} \\ \boxed{ \begin{array}{l} \text{\scriptsize natural numbers ($\mathbb{N}$)} \end{array}} \end{array}} \end{array}} \end{array}} & \boxed{ \begin{array}{c} \text{irrational numbers} \\ \ \\ \ \\ \ \\ \ \end{array}} \end{array}}

<h3>Answer: B) Experiment</h3>

Reason:

Whenever you have two groups like this, one labeled the treatment group and the other the control group, we have an experiment gong on.

The treatment group gets the actual medication that is being tested. The control group gets a fake medication, aka placebo. Usually a placebo is meant for humans because it's more of a psychological factor. With cats, it likely won't affect them. However, such practices of having two groups like this is standard no matter what group of subjects you're testing.

The idea is that if the treatment group has better results compared to the placebo group, then it's likely the medication works.

1/4 times 2 2/3 = 2/3

Change from a mixed number to improper fraction: 1/4 times 8/3

Multiply across so 1x8/4x3 to get 8/12

Simplify to 2/3

Answer:

<h3>Step-by-step explanation: for #2, look at 6 3/4 and make it into a decimal. Do the same to 7 1/2. Compare them both to see which one is shorter by subtracting 6 3/4 from 7 1/2 and when you get your answer for that, make that into a fraction. Predict that 6 3/4 is shorter because of how much less it is compared to 7 1/2.  (I hope I helped you in some way. Good luck!)</h3>
