$- \frac{17 \cdot 2}{6 \cdot 2} + \frac{5}{4} \cdot \frac{3}{3}$

Multiply

$6$ by

$2$ .

$- \frac{17 \cdot 2}{12} + \frac{5}{4} \cdot \frac{3}{3}$

Multiply

$\frac{5}{4}$ by

$\frac{3}{3}$ .

$- \frac{17 \cdot 2}{12} + \frac{5 \cdot 3}{4 \cdot 3}$

Multiply

$4$ by

$3$ .

$- \frac{17 \cdot 2}{12} + \frac{5 \cdot 3}{12}$

Step 7
