Question

1. $\frac{2}{7}q=3$

Explanation:

Step1: Isolate q via reciprocal multiply

Multiply both sides by $\frac{7}{2}$:
$$q = 3 \times \frac{7}{2}$$

Step2: Calculate the product

Multiply numerators, keep denominator:
$$q = \frac{3 \times 7}{2} = \frac{21}{2}$$

Answer:

$\frac{21}{2}$ or $10.5$
