If 25$\%$ of a number is the same as 20$\%$ of 30, what is the number?
Let me call that number x. Then I can write an equation: 25$\%$ of x equals 20$\%$ of 30. 25$\%$ is the same as 1/4, and 20$\%$ is the same as 1/5. So the equation is: 1/4 x = 1/5 (30). To solve for x, I can multiply both sides by the reciprocal of 1/4, which is 4. This gives me: x = 4 (1/5) (30). I can simplify this by multiplying 4 and 1/5 first, which is 4/5. Then I can multiply 4/5 and 30, which is 24. So x = 24.
