Unit 7 Homework KeyLesson 7.1Identify which of the following numbers are rational or irrational.31. 252. 243. 364. 645. tional7. 0.458. 0. 2̅9. 4910. 1811. ational̅̅̅14. 0. ̅4215. 0.3916. 10017. 1618. Rational8112119. If the number 0.77 is displayed on a calculator that can only display ten digits, do we know whether it isrational or irrational? In one complete sentence explain why.Rational because it terminates (or repeats the digit zero).20. If the number 0.123456789 is displayed on a calculator that can only display ten digits, do we know whetherit is rational or irrational? In one complete sentence explain why.We don’t know. The decimal could repeat later making it rational or could never repeat making it irrational.21. If the number 0.987098709 is displayed on a calculator that can only display ten digits, do we know whetherit is rational or irrational? In one complete sentence explain why.Our best guess is that it is rational because there appears to be a pattern, but we can’t be sure.22. If the number 0.425364758 is displayed on a calculator that can only display ten digits, do we know whetherit is rational or irrational? In one complete sentence explain why.We don’t know. The decimal could repeat later making it rational or could never repeat making it irrational.1
