Answer:

Table shown below

Step-by-step explanation:

To solve this problem let's use proportions.

If 2 pounds of grapes cost $6, half the amount will cost half the dollars, so the last row will have $3 in the price

For the second row, we know the price is $1, that is, one-sixth of the original given price. It should correspond to one-sixth of the amount of grapes or 2/6 pounds.

Simplifying the fraction, we get 1/3 or 0.33 pounds

5/10 is 1/2 or .5 As a percentage, this is .5%, and as a decimal it's .005. Using this in an equation, .005x = 12. Divide 12 by .005 to get 2400

**Answer:**

11/8 or 1 & 3/8

**Step-by-step explanation:**

5 & 2/8=21/4

3&7/8=31/8

21/4-31/8=11/8 or 1 & 3/8
