Write two fractions whose quotient is4528​. The Correct Answer and Explanation is : To find two fractions whose quotient is ( \frac{45}{28} ), we can use the relationship that the quotient of two fractions ( \frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c} ). Thus, we need to determine two fractions ( \frac{a}{b} ) and (
