simplify 3*(-2/3)

Solution

simplify

3 \cdot (- \frac{2}{3})

- 2

Solution steps

3 (- \frac{2}{3})

Apply rule:

a (- b) = - ab

3 (- \frac{2}{3}) = - 3 \cdot \frac{2}{3}

= - 3 \cdot \frac{2}{3}

Convert element to fraction:

3 = \frac{3}{1}

= - \frac{3}{1} \cdot \frac{2}{3}

Cross-cancel common factor:

3

= - \frac{2}{1}

Divide the numbers:

- \frac{2}{1} = - 2

= - 2

\frac{1 - sin ^{2} ( x )}{sin ^{2} ( x )}

\frac{x ^{2}}{16} - \frac{30}{4} x + 225

x^{4} - x^{3} - 3 x^{2} + x + 2

\frac{4}{5} \times 10

\frac{6}{5} \div 2
