rebecca bought 1 1/2 pounds of grapes, they cost her $3.72 per pound. What was the total cost of her grapes?
2.48
The answer is 2.48 because you would have to turn $3.72 into a fraction which is 3 72/100 then you have to turn 1 1/2 & 3 72/100 into an improper fraction. You do KEEP CHANGE FLIP and you should get 300/744. After you divide 744 divided by 300 to get $2.48.

To find the total cost of Rebecca's grapes, we need to multiply the weight of the grapes by the cost per pound.
First, let's convert the mixed number 1 1/2 into an improper fraction:
1 1/2 = (1 * 2 + 1) / 2 = 3/2
Now we have the weight of the grapes as 3/2 pounds.
Next, we can multiply the weight by the cost per pound:
Total cost = 3/2 * $3.72
To multiply fractions, we multiply the numerators (top numbers) together and the denominators (bottom numbers) together:
Total cost = (3 * $3.72) / 2
Multiplying the numbers, we get:
Total cost = $11.16 / 2
To divide by a fraction, we can "flip" the fraction we're dividing by and then multiply:
Total cost = $11.16 * (1/2)
Multiplying the numbers, we get:
Total cost = $11.16 / 2 = $5.58
Therefore, the total cost of Rebecca's grapes is $5.58.
