Full solution

Q.

\dfrac{8}{3} = \dfrac{12}{n}

Cross-multiply: We have the equation $\dfrac{8}{3} = \dfrac{12}{n}$ . To find the value of n, we need to solve for n by cross-multiplying the fractions. $\newline$ Cross-multiply: $8 \times n = 12 \times 3$ .
Perform multiplication: Perform the multiplication on the right side of the equation. $\newline$ $12 \times 3 = 36$ . $\newline$ Now the equation is $8n = 36$ .
Isolate n: To isolate n, divide both sides of the equation by $8$ . $\newline$ $\dfrac{8n}{8} = \dfrac{36}{8}$ .
Perform division: Perform the division to find the value of n. $\newline$ $n = \dfrac{36}{8}$ . $\newline$ $n = 4.5$ .
