Alright, we can start by dividing 16 into chunks, and since 12 is a multiple of 4, we're just gonna divide by four
16/4=4
So there are four fours in sixteen, cool. Now 100 divided what would equal 4?
100/4=25
Ok. So each four is 25 percent. There are three fours in twelve so
3*25=75
Green=75%
and four only has one four in it so
1*25=25
Yellow=25%
