This week we learnt about rational numbers.
A rational number is a number that can be simplified as a fraction.
eg.)0.354354354... is a rational number because it keeps repeating 354, as a fraction it would be 354/999. 4 is a rational number because its 4.000 and zero is repeating, its fraction would be 4/1.
a rational number is not a number that is not repeating the same number
eg.) pie is not a rational number because it doesn't repeat the same number.
a rational number can be ether a decimal, fraction, or an integer.
There is a rule of "9", and the rule is:
1.) figure out if its repeating one. two, three...digit numbers.
2.) rewrite what is repeating, and have 9 as the denominator if it is a one digit #, if it's a two digit # it would be 99. ect.
eg,) 0.354354354, since its a three digit # it would be 354/999.
