Answer :

16/8=2/1=2

so just factor out the ones so for example

4/8=1/2 because 1/2 times 4/4=4/8 and 1/2 times 4/4=1/2 times 1=1/2

so 16/8=
factor
16=2 times 2 times 2 times 2
8= 2 times 2 times 2
16/8=2/1 times 2/2 times 2/2 times 2/2=2/1 times 1 times 1 times 1=2/1=2
16/8 in simplest form is 2/1 or 2 because you have to divide it by 8/8 or divide 16 and 8 by 8
