To which subset of real numbers does -3 belong?
inessss [21]
<h3>Answer: C) integers and rational numbers</h3>

Explanation:

The set of integers is {..., -3, -2, -1, 0, 1, 2, 3, ...} basically any number that does not have a decimal or fractional part to it. We can say that this set is composed of positive and negative whole numbers along with 0. So this is why -3 is in the set of integers.

The value -3 is not in the set of whole numbers because the set of whole numbers is {0, 1, 2, 3, 4, 5, 6, ...}, so this rules out choice D.

Choice B is also eliminated because -3 is a rational number. We can write -3 as a fraction of two integers, example: -3 = -3/1. Any rational number is not irrational, and vice versa.

Choice A is ruled out because it's not the most complete answer (though its technically true).

In the 3rd century bc the egyptians used their body parts to measure things.Why do you think peoplebinvented measurement system
Bingel [31]
In order to have an accurate measurement system, humans would’ve had to have created one. Although body parts could be used to measure things, the lengths would’ve been different everytime. This is because no human’s body part is the exact same length as another’s. Everybody’s bone structure is different so in order to create a universally correct measurement system, humans had to invent a new one.
