Question

1. To which sets of numbers does the square root of 100 belong?

I. rational numbers
II. integers
III. whole numbers

A. I and II only
B. II and III only
C. I and III only
D. I, II,and III

Answer 1

D. All
Root 100= 10
10 is a rational number, an integer, and a whole number

Answer 2

Numbers are classified according to type. The first type of number is the first type you ever learned about: the counting, or "natural" numbers:

1, 2, 3, 4, 5, 6, ...

The next type is the "whole" numbers, which is the natural numbers together with zero:

0, 1, 2, 3, 4, 5, 6, ...

Then come the "integers", which are zero, the natural numbers, and the negatives of the naturals:

..., –6, –5, –4, –3, –2, –1, 0, 1, 2, 3, 4, 5, 6, ...

The next type is the "rational", or fractional, numbers, which are technically regarded as ratios (divisions) of integers. In other words, a fraction is formed by dividing one integer by another integer.

Note that each new type of number contained the previous type within it. The wholes are just the naturals with zero thrown in. The integers are just the wholes with the negatives thrown in. And the fractions are just the integers with all their divisions thrown in. (Remember that you can turn any integer into a fraction by putting it over the number 1. For example, the integer 4 = 4/1, which is a fraction.) Since you learned these number types in the same order as their hierarchy, it's easy to remember their order.

Answer 3

D; The square root of 100 could be either 10 or -10, and both can be expressed as a ratio or franction (thus, choice I).

Integers are just whole numbers (including negative numbers), and thus, the square root of 100 can also be choice II.

10 or -10 is a whole number, and thus, choice III also applies.

Therefore, the answer is D -- I, II, and III.

Answer 4

well all of them so choice D, 100s square root comes to 10,or -10

Answer 5

D

Answer 6
