Answer:
To find the value of \( x \) in the equation \(\dfrac{5}{15} = \dfrac{x}{30}\), we can solve for \( x \) by cross-multiplying: \[ 5 \times 30 = 15 \times x \] \[ 150 = 15x \] Now, divide both sides by 15 to solve for \( x \): \[ x = \dfrac{150}{15} = 10 \] Therefore, the value of \( x \) is 10.
