Carlo buys $14.40 worth of grapefruit. Each grapefruit costs $0.80.

a. How many grapefruits does Carlo buy?
b. At the same store, Kahri spends one-third as much money on grapefruit as Carlo. How many
grapefruits does she buy?

(a) 14.40/0.80 = ____

(b) 1/3 the money, so 1/3 the fruits.

1/3 * $14.40

To find the answers to these questions, we need to divide the total amount spent by the cost per grapefruit. Let's solve them step by step:

a. How many grapefruits does Carlo buy?
To find the number of grapefruits Carlo bought, we need to divide the total amount spent by the cost per grapefruit.
Total spent = $14.40
Cost per grapefruit = $0.80

Number of grapefruits Carlo bought = Total spent / Cost per grapefruit

Number of grapefruits Carlo bought = $14.40 / $0.80

Now, let's divide 14.40 by 0.80 to find the number of grapefruits Carlo bought.
Dividing 14.40 by 0.80, we get: 18.

Therefore, Carlo bought 18 grapefruits.

b. How many grapefruits does Kahri buy?
Kahri spends one-third as much money on grapefruit as Carlo. So, to find the number of grapefruits Kahri bought, we need to divide Carlo's total spent by 3, and then divide that by the cost per grapefruit.

Kahri's total spent = Carlo's total spent / 3
Kahri's number of grapefruits = Kahri's total spent / Cost per grapefruit

Kahri's total spent = $14.40 / 3

Now, let's calculate Kahri's total spent.
Dividing 14.40 by 3, we get: 4.80.

Kahri's number of grapefruits = 4.80 / $0.80

Now, let's calculate the number of grapefruits Kahri bought.
Dividing 4.80 by 0.80, we get: 6.

Therefore, Kahri bought 6 grapefruits.
