Question
40% of John's marbles is the same as 25% of Jack's marbles. John has 20 marbles. How many marbles does Jack have?
Solution
First, we need to find out what 40% of John's marbles is. Since John has 20 marbles, we calculate 40% of 20.
40% of 20 = 0.40 * 20 = 8 marbles
This means that 8 of John's marbles is the same as 25% of Jack's marbles.
To find out how many marbles Jack has, we set up the equation 25/100 * x = 8, where x is the number of Jack's marbles.
Solving for x gives us x = 8 / (25/100) = 32
So, Jack has 32 marbles.
