Question

19/3÷3 reduce to lowest terms

Answer 1

19/9 because 19/3 times 1/3 is 19/9

Answer 2

$\bf \cfrac{19}{3}\div 3\implies \cfrac{19}{3}\div \cfrac{3}{1}\implies \cfrac{19}{3}\cdot \cfrac{1}{3}\implies \cfrac{19}{9}\implies 2\frac{1}{9}$

let's bear in mind that 19 is prime, so is not factorable.
