Question

1. \frac{7}{n} = \frac{8}{7}

Explanation:

Step1: Identify the equation

The equation is $\frac{7}{n} = \frac{8}{7}$.

Step2: Cross - multiply

Cross - multiplying gives $7\times7 = 8\times n$, which simplifies to $49 = 8n$.

Step3: Solve for n

To solve for $n$, divide both sides of the equation by 8. So, $n=\frac{49}{8}$.

Answer:

$n = \frac{49}{8}$
