How do you check if a number is rational? How do you check if a number is irrational?

Thanks!

P. S. 50 points & brainiest to whoever answer first!

Any number that is able to be written down as a fraction/ratio is a ration number.

An irational number is a number hat has a decimal, but can't be written as a fraction. Ex: Pi/π

could u provide us some answer choices or hmm idk maybe a table for us to anser with ? ?

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
