$$6\ \frac{12}{12}\ -\ 3\ \frac{3}{12}$$ = $$3\ \frac{9}{12}$$

Lowest Term

$$3\ \frac{9\div3}{12\div3}$$ = $$3\ \frac{3}{4}$$

$$\frac{8}{1}\ x\ \frac{21}{4}$$ = $$\frac{2}{1}\ x\ \frac{21}{1}$$

Since the denominator is 1 you can proceed by multiplying the numerator

$$2\ x\ 21\ =42$$

$$\frac{12}{6}\ x\ \frac{18}{11}=$$

Divide 12 by 6

$$\frac{2}{1}\ x\ \frac{18}{11}$$

Proceed to multiplication

$$\frac{2}{1}\ x\ \frac{18}{11}=\ \frac{36}{11}$$

Express your answer in Mixed Number by dividing the numerator by the denominator

$$\frac{36}{11}\ =\ 3\ \frac{\left(36-33\right)}{11}$$

= $$3\ \frac{3}{11}$$

Divide 22 by 80

$$22\div80=0.275$$

Divide the numerator by the denominator.

$$\frac{62}{9}$$

Write the whole number on the left side then the reminder as the new numerator then copy/use the same denominator.

$$6\ \frac{8}{9}$$

Identify the height and base then use it to solve for area of triangle.

Area of triangle = $$\frac{1}{2}base\ x\ height$$ or $$\frac{\left(base\ x\ height\right)}{2}$$

$$\frac{\left(4x8\right)}{2}=\frac{32}{2}$$

Proceed by dividing the numerator by the denominator

$$32\div2\ =\ 16$$
