What is 36/80 in lowest terms fraction wise

Mekhanik [1.2K]

To simplify a fraction (reduce it to lowest terms), you divide
the numerator and denominator both by their greatest common
factor. (That's why you learn 'greatest common factor' before
you learn to simplify fractions.)

The greatest common factor of 36 and 80 is 4 .

Divide the top and bottom of 36/80 by 4, and you'll have the
fraction in lowest terms.
