Answer:

Step-by-step explanation:

Count the number of perfect squares between 1 and 100. They are the rational ones. I guess you can't count 1 or 100 because the directions for the question says "between." but we can add 2 more to whatever answer we get.

4 9 16 25 36 49 64 81 And that's all there are. These are the rational ones there are only 8 of them. There are far more irrationals than rationals.

The statement is true.

Which expression represents rational numbers? Select all that apply

Vladimir79 [104]

Answer:

1. $\sqrt{100} \sqrt{100}$

2. 13.5 + $\sqrt{81}$

3. $\sqrt{9} + \sqrt{729}$

6. $\frac{3}{5} + 2.5\\\frac{3+12.5}{5}\\\frac{15.5}{5}\\= 3.1$

These four options are rational;

Step-by-step explanation:

1. $\sqrt{100} \sqrt{100}$ equals to 10 * 10 = 100 which is rational

2. 13.5 + $\sqrt{81}$ equals 13.5 + 9 = 22.5

3. $\sqrt{9} + \sqrt{729}$ -- 3+27 = 30

6. $\frac{3}{5} + 2.5\\\frac{3+12.5}{5}\\\frac{15.5}{5}\\= 3.1$

Option 4 and 5 are irrational because they include $\sqrt{353}$ and $\sqrt{216}$ which are not a perfect square and their answers will be non recurring and non terminating decimal fraction.
