To find out how many pounds of candy each friend will have, you need to divide the total amount of candy by the number of friends.

Kathleen bought 4 1/2 pounds of candy. First, let's convert that to an improper fraction to make the division easier.

4 1/2 is the same as (4 × 2 + 1)/2, which equals 9/2 pounds of candy because 4 times 2 is 8, plus 1 makes 9, and we keep the original denominator of 2.

Now that we have an improper fraction, we can divide this by the 3 friends.

(9/2) ÷ 3

It is easier to divide by a whole number if we convert it into a fraction, and any whole number can be written as itself over 1.

So now the equation looks like this: (9/2) ÷ (3/1)

When dividing fractions, we multiply by the reciprocal of the divisor. The reciprocal is what you get when you flip the numerator and the denominator of a fraction.

The reciprocal of 3/1 is 1/3. So:

(9/2) × (1/3)

Now we multiply the numerators together, and the denominators together:

9 × 1 = 9 2 × 3 = 6

So: (9/2) × (1/3) = 9/6

Now we simplify the fraction:

9/6 can be simplified by dividing both the numerator and the denominator by their greatest common factor, which is 3.

9 ÷ 3 = 3 6 ÷ 3 = 2

So, 9/6 simplifies to 3/2, which can also be written as 1 1/2 or one and a half pounds.

Therefore, each of Kathleen's 3 friends will get 1 1/2 pounds of candy to share.
