Question

$$2 \frac { 3 } { 7 } - 1 \frac { 5 } { 7 }$$

Evaluate

$\frac{5}{7}\approx 0.714285714$

Solution Steps

Multiply $2$ and $7$ to get $14$.

$$\frac{14+3}{7}-\frac{1\times 7+5}{7}$$

Add $14$ and $3$ to get $17$.

$$\frac{17}{7}-\frac{1\times 7+5}{7}$$

Multiply $1$ and $7$ to get $7$.

$$\frac{17}{7}-\frac{7+5}{7}$$

Add $7$ and $5$ to get $12$.

$$\frac{17}{7}-\frac{12}{7}$$

Since $\frac{17}{7}$ and $\frac{12}{7}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{17-12}{7}$$

Subtract $12$ from $17$ to get $5$.

$$\frac{5}{7}$$

Factor

$\frac{5}{7} = 0.7142857142857143$
