$\color {magenta}\frac{1\times1.4}{2}\color{black}=\color{cyan}1\times0.7\color{black}=\color{magenta}\textbf{0.7}cm^2$

$\color{blue}\textbf{I am using} \color{blue }\LaTeX$

$\frac{2}{3}\times \frac{3}{4}$

=$\frac{2\times3}{3\times4}$

$\frac{6}{12}$

=$1\over2$

Use sine law and cosine law.

20/15 = 4/3

Just think about it, how can you divide 3 cookies to 0 friends?

$-\frac{5}{6}:\frac{5}{12}= -10:5=-2:1$

sin 1° = 0.01745.......

sin 1 radians = 0.8415......
