HOW YOU CAN TELL THAT 31 33 IS IN SIMPLEST FORM

Answer 1

Do you mean 31/33?
Since 31 is a prime number, and not a factor of 33, there are no common factors to cancel out of both numerator and denominator. Therefore the fraction 31/33 is in lowest terms (simplest form) already.

If it was 30/33, you could reduce it to 10/11, by canceling out the common factor 3.

Answer 2

I agree with ^ and fractions are not my favorite units but I'm only in 5th grade and have a lot of fractions in my future. Just try and trust me ( a complete stranger ). :)
