To find out how many crackers Daphne has, we need to determine the ratio between the number of crackers William has and the number of crackers Daphne has.
The given ratio is 3:5, which means that for every 3 crackers William has, Daphne has 5 crackers.
Let's suppose that William has 3x crackers.
Therefore, Daphne has 5x crackers.
Now, we know that the total number of crackers is 48. Therefore, we can set up the following equation:
3x + 5x = 48
Combining like terms:
8x = 48
Dividing both sides by 8:
x = 6
Now, substituting the value of x back into our equations, we find that William has:
3x = 3 * 6 = 18 crackers
And Daphne has:
5x = 5 * 6 = 30 crackers
Therefore, Daphne has 30 crackers.
