i think it would be 4/15 because science is 6/15 and fiction is 5/15

The way I would do this problem would be to find a common denominator for both of the fractions.

5/15

6/15

And then we can find out how many books there are left.

5/15 + 6/15 is 11/15

11/15 books are about science and biography, the other 4/15 are fiction.

3. Identify the subsets of real numbers that apply to /100/5
Alina [70]

Using number sets, it is found that the correct classification of the number is:

C. rational number, integer, whole number, natural number , real number.

Numbers are classified as:

  • Whole, which is all positive numbers and zero, also called natural.
  • Integers, which is the set of whole numbers plus negatives.
  • Rational, which is the set of integer numbers plus terminating or repeating decimals.
  • Irrational, which are non terminating decimals.
  • Real, which are the sum of rational and irrational.

In this problem, the number given is:

\frac{100}{5} = 20

  • Which is a whole(natural) number, thus it is also integer, rational and real, and the correct option is C.
