Problem Analysis

To solve this problem, we need to determine the number of bouquets that can be made using 14 yellow roses and 28 red roses, with each bouquet containing 7 roses.

Solution 1: Division

One way to solve this problem is by dividing the total number of roses by the number of roses in each bouquet.

1. Calculate the total number of roses: 14 yellow roses + 28 red roses = 42 roses. 2. Divide the total number of roses by the number of roses in each bouquet: 42 roses ÷ 7 roses/bouquet = 6 bouquets.

Therefore, 6 bouquets can be made using 14 yellow roses and 28 red roses.

Solution 2: Subtraction

Another way to solve this problem is by subtracting the number of roses in each bouquet from the total number of roses until no more bouquets can be made.

1. Start with the total number of roses: 14 yellow roses + 28 red roses = 42 roses. 2. Subtract the number of roses in each bouquet: 42 roses - 7 roses/bouquet = 35 roses. 3. Repeat the subtraction until no more bouquets can be made: 35 roses - 7 roses/bouquet = 28 roses. 4. Since 28 roses is not enough to make another bouquet, the process stops.

Therefore, 6 bouquets can be made using 14 yellow roses and 28 red roses.

Solution 3: Integer Division

We can also use integer division to solve this problem.

1. Calculate the total number of roses: 14 yellow roses + 28 red roses = 42 roses. 2. Use integer division to divide the total number of roses by the number of roses in each bouquet: 42 roses ÷ 7 roses/bouquet = 6 bouquets.

Therefore, 6 bouquets can be made using 14 yellow roses and 28 red roses.

Solution 4: Modulo Operator

We can also use the modulo operator to solve this problem.

1. Calculate the total number of roses: 14 yellow roses + 28 red roses = 42 roses. 2. Use the modulo operator to find the remainder when dividing the total number of roses by the number of roses in each bouquet: 42 roses % 7 roses/bouquet = 0. 3. Since the remainder is 0, it means that no roses are left after making the bouquets.

Therefore, 6 bouquets can be made using 14 yellow roses and 28 red roses.

Summary

In summary, using different methods, we have determined that 6 bouquets can be made using 14 yellow roses and 28 red roses, with each bouquet containing 7 roses.
