Eric has a riddle: "I am thinking of a fraction that is equivalent to 25 and the numerator is 18 less than the denominator." What is Eric's fraction? Explain how you know
The fraction that Eric is thinking of is 7/28. This is because, according to his riddle, the numerator is 18 less than the denominator. Therefore, the numerator must be 7 (28 - 18 = 10) and the denominator must be 28. And since 7/28 can be simplified to 1/4, which is equivalent to 25, we know that this is the correct fraction.
