A rational number is any number that can be represented as a fraction.
9.5 = 19/2
9.2 = 46/5

An irrational number cannot be represented as a fraction and has infinite number of decimal places. Most commonly seen in square roots.
9^2 = 81
10^2 = 100
Therefore the square root of any integer from 81 and 100 will be between 9 and 10 and also be an irrational number.
\sqrt{87} , \sqrt{93}

Answer:

Step-by-step explanation:

9/5 is the ratio tea/coffee

let x be the one who preferred coffee and x+36 preferred tea

x=180/4=45

x=45 coffee

x+36=45+36=81

45+81=126

check : 81/45= 9/5
