You have 16 cds to put in your empty five shelf cd rack. can you place the cds so that each shelf contains three or fewer cds? can you arrange them so that each shelf contains exactly three?

No, you can not it ends up making .3125     

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
