Let's practice completing table problems with the use of division. We can do this by dividing multiple unit values by the number of units to determine the unit cost, as in our table below.
| Cost for 1 | Cost for 6 | |
| Jacket | $ | $120 |
| Sweater | $ | $150 |
This table shows us the cost of 6 jackets and 6 sweaters. It doesn't show us the cost for 1 jacket and 1 sweater. Since we know the cost of 6 jackets, we divide by 6 to get the cost of 1 jacket. We know that 6 jackets cost $120. So we divide 120 by 6 (120 ÷ 6). What is the answer?
The cost of 1 jacket is $20. Next, we find the cost of 1 sweater. We know that 6 sweaters cost $150. We divide 150 by 6 (150 ÷ 6). How much does 1 sweater cost?
One sweater costs $25.
| Cost for 1 | Cost for 6 | |
| Jacket | $20 | $120 |
| Sweater | $25 | $150 |
Always remember that, to know the unit cost of one item, divide the total cost by the number of items.
| Cost for 1 | Cost for 5 | |
| Steak | $ | $35 |
| Chicken breast | $ | $25 |
The table above shows the cost of 5 steaks and 5 chicken breasts. It doesn't show us the price of 1. Because we know the price of 5 steaks, we can divide the total cost of the steaks by 5 to find out how much 1 steak costs.
Next, we do the same to get the cost of one chicken breast.
Now we know how much 1 steak and 1 chicken breast cost. We can complete the table.
| Cost for 1 | Cost for 5 | |
| Steak | $7 | $35 |
| Chicken Breast | $5 | $25 |
