Answer 1

Answer:

The correct answer is Option C.

Explanation:

1) Simplify 9/60 to 3/20.

$\frac{x}{24} - \frac{x}{30} = \frac{3}{20}$

2) Simplify x/24 - x/30 to x/120.

$\frac{x}{120} = \frac{3}{20}$

3) Multiply both sides by 120.

$x = \frac{3}{20} \times 120$

4) Use this rule: a/b × c = ac/b.

$x = \frac{3 \times 120}{20}$

5) Simplify 3 × 120 to 360.

$x = \frac{360}{20}$

6) Simplify 360/20 to 18.

$x = 18$

Therefor, the answer is option C. 18.
