16/108=

This next step u have to do long division,

Put 16 on the outside and then put 108 in the inside, then ask yourself can 16 go int 10 it can’t, than u have 108 can this go into 16 yes it can go into 6 times so ur reminder is 12

16 divided by 4 over 12 divided by 4 = 4 over 3

4 divided by 3 = 1

4 divided by 3 = 1 1/3- this can reduced so

4 divided by 3 = 1.3333333 is ur answer
