1)
23.5/4.98=4.8→4
So the greatest number of luncheon specials they can buy with money in their luncheon account is 4
2)
36/0.375=96
so I can fit on the shelf with 96 CDs
23.5/4.98=4.8→4
So the greatest number of luncheon specials they can buy with money in their luncheon account is 4

If you have learn division, the calculation is straightforward.
23.50/4.89 = 4.8
36/0.375=96
So 1). They can buy 4 luncheon specials.
2). The shelf can fit 96 CD cases.
23.50/4.89 = 4.8
36/0.375=96
So 1). They can buy 4 luncheon specials.
2). The shelf can fit 96 CD cases.
