Question

$$\frac { 10 x + 1 } { 3 + \frac { 1 } { 2 } }$$

Evaluate

$\frac{20x+2}{7}$

Solution Steps

Convert $3$ to fraction $\frac{6}{2}$.

$$\frac{10x+1}{\frac{6}{2}+\frac{1}{2}}$$

Since $\frac{6}{2}$ and $\frac{1}{2}$ have the same denominator, add them by adding their numerators.

$$\frac{10x+1}{\frac{6+1}{2}}$$

Add $6$ and $1$ to get $7$.

$$\frac{10x+1}{\frac{7}{2}}$$

Divide $10x+1$ by $\frac{7}{2}$ by multiplying $10x+1$ by the reciprocal of $\frac{7}{2}$.

$$\frac{\left(10x+1\right)\times 2}{7}$$

Use the distributive property to multiply $10x+1$ by $2$.

$$\frac{20x+2}{7}$$
