Select the correct answer.

If [tex]\frac{3}{4}[/tex] and [tex]\frac{12}{x}[/tex] are equivalent, what is the value of [tex]x[/tex]?

A. 48
B. 36
C. 24
D. 16



Answer :

To determine the value of [tex]\( x \)[/tex] such that the fractions [tex]\(\frac{3}{4}\)[/tex] and [tex]\(\frac{12}{x}\)[/tex] are equivalent, we need to set up an equation based on the equality of the fractions. Here’s the detailed step-by-step process:

1. Write down the equivalence of the fractions:
[tex]\[ \frac{3}{4} = \frac{12}{x} \][/tex]

2. To eliminate the fractions, use cross-multiplication. This method involves multiplying the numerator of one fraction by the denominator of the other fraction and setting the products equal to each other:
[tex]\[ 3 \times x = 4 \times 12 \][/tex]

3. Perform the multiplication on the right-hand side:
[tex]\[ 3x = 48 \][/tex]

4. To solve for [tex]\( x \)[/tex], divide both sides of the equation by 3:
[tex]\[ x = \frac{48}{3} \][/tex]

5. Simplify the division to find the value of [tex]\( x \)[/tex]:
[tex]\[ x = 16 \][/tex]

Therefore, the value of [tex]\( x \)[/tex] that makes the fractions [tex]\(\frac{3}{4}\)[/tex] and [tex]\(\frac{12}{x}\)[/tex] equivalent is [tex]\( 16 \)[/tex].

Hence, the correct answer is:
D. 16
