An integer is defined as a whole number (not a fraction, or decimal...). Negative whole numbers are also considered integers. So which option(s) do you think are correct for Q1?

2. supercait10

B. Half of the irrational numbers are also rational numbers. C. One-third of the irrational numbers are also rational numbers. D. Irrational numbers cannot be classified as rational numbers. Question 4. How would you change this sentence to a true statement? A. Every Irrational number is a rational number B. Every irrational number is a real number. C. Every irrational number is a whole number. D. Every irrational number is a perfect square. $\sqrt{7}$ for Question 1, Choice 3 so u know

3. supercait10

um A?

4. FireKat97

Yup thats correct

5. FireKat97

For Q2, we have already established what an integer is, but do you know what rational and irrational numbers are?

6. supercait10

not really I was just thrown into Algebra and also it doesn't help much I suffered from a concussion so can't remember half the stuff I learn in school

7. FireKat97

oh thats terrible :/ Anyway, a rational number is one which can be written in fraction form, where both, the numerator and denominator are whole numbers.. e.g. 2/3, 4/7 and irrational numbers are those which cannot be written into fractions like above, for e.g. π, because π is a never ending number, and you cannot write a never ending number in fraction form

8. supercait10

okay

9. FireKat97

and do you know the definition of real numbers?

10. supercait10

include all rational and irrational numbers

11. FireKat97

12. supercait10

umm a maybe

13. FireKat97

Yup thats correct!

14. FireKat97

and what do you think the answer to Q3 would be?

15. supercait10
