Best ResponseYou've already chosen the best response.1You would first assume 50/2 just because it's negative, but that is also a rational number, but one of the numbers here isn't rational...so what would the answer be?

Best ResponseYou've already chosen the best response.2hint: \[\Large 50.\overline 1 = \frac{{501  50}}{9}\]

Best ResponseYou've already chosen the best response.2hint: we can write this \[\Large \begin{gathered} 50.\overline 1 = \frac{{501  50}}{9} = \frac{{451}}{9} \hfill \\ \hfill \\  \frac{{50}}{2},\quad  50.1 =  \frac{{501}}{{10}} \hfill \\ \end{gathered} \]

Best ResponseYou've already chosen the best response.2furthermore, we are not able to find a pair of integer numbers, say m, and n, such that: \[\Large \sqrt 2 = \frac{m}{n}\]

Best ResponseYou've already chosen the best response.2oops.. \[\Large \sqrt {50} = \frac{m}{n}\]

Best ResponseYou've already chosen the best response.2in other words, the first three numbers can be expressed as ratios, whereas the fourth number, namely sqrt(50), can not be expressed as a ratio, so what can you conclude?

Best ResponseYou've already chosen the best response.0but why ? @Michele_Laino

Michele_Laino

Best ResponseYou've already chosen the best response.2because sqrt(50) we can not find a pair of integers, (m,n) such that: \[\Large \sqrt {50} = \frac{m}{n}\] in other words sqrt(50) is an irrational number, whereas the others three numbers are rational numbers, since they can be expressed as fractions

Best ResponseYou've already chosen the best response.1Easily put, rational numbers are any number that can be made by dividing two integers, but \[\sqrt{50}\] can't be, same reason for pi, that is not a rational number,

Best ResponseYou've already chosen the best response.0Which mathematical symbol would best fill in the blank to compare the two real numbers? 7.6 repeating blank square root 55 < > = ≈

Best ResponseYou've already chosen the best response.2what do you mean with 7.6 repeating blank?

anonymous

Best ResponseYou've already chosen the best response.0\[7.6 ____ \sqrt{55}\]

Michele_Laino

Best ResponseYou've already chosen the best response.2do you mean 7.6?

Michele_Laino

Best ResponseYou've already chosen the best response.2if we make the square of the two numbers, we get this: \[\Large {7.6^2} = {\left( {\frac{{76}}{{10}}} \right)^2} > 55\] am I right?

Best ResponseYou've already chosen the best response.2As before I consider the square of each number: \[\Large \begin{gathered}  \frac{5}{6} \to {\left( {  \frac{5}{6}} \right)^2} = \frac{{25}}{{36}} \hfill \\ \hfill \\  5 \to {\left( {  5} \right)^2} = 25 = \frac{{900}}{{36}} \hfill \\ \hfill \\  \sqrt {26} \to 26 = \frac{{936}}{{36}} \hfill \\ \hfill \\  \frac{{31}}{6} \to {\left( {  \frac{{31}}{6}} \right)^2} = \frac{{961}}{{36}} \hfill \\ \end{gathered} \]

Best ResponseYou've already chosen the best response.2furthermore, you have to keep in mind that your numbers are negative, so the number which has the square bigger than others, is the first number in your sequence

Best ResponseYou've already chosen the best response.0its the last answer 5/6 5  square 26 31/6

Michele_Laino

Best ResponseYou've already chosen the best response.2no, since 31/6 has the square bigger than others, so it is the first number of your sequence, so we have: 31/6,...

Michele_Laino

Best ResponseYou've already chosen the best response.2the order is reversed, since your numbers are all negative numbers
