Answer: 9x ÷ 4x
See explanation below.
Step-by-step explanation: To get any expression that is the same as 9÷4, you have to make that expression equivalent to the original, in this they name the same number. Equivalent fractions series of fractions that name the same number. To get equivalent fractions, numerator and the denominator of the original fraction must be multiplied by the same non-zero whole number. Since the non-zero whole numbers are the same (e.g. 4÷4), dividing out gives 1 and multiplying a fraction by 1 does not change its value.
Let x represent the non-zero whole number. To generate the expression using x, we have
9x ÷ 4x
