Ryan has 8 kittens. Two are white. What fraction of the kittens are not white? Write in simplest from.

maxonik [38]

Number of kittens Ryan has = 8

Number of white kittens = 2

Number of not white kittens = 8 -2 = 6

Fraction of number of not white kittens = 6/8

To write the fraction in lowest form find the greatest common factor of numerator and the denominator. Divide the numerator and the denominator by the greatest common factor .

Now the greatest common factor of 6 and 8 is 2.

$\frac{6}{8}$ = $\frac{6\div 2}{8\div 2}$ = $\frac{3}{4}$
