Solve 4+4/5(-5/2)3+2div2/3-2left(1/2-frac{2}{3}right)

$$4+ \frac{ 4 }{ 5 } (- \frac{ 5 }{ 2 } )3+2 \div \frac{ 2 }{ 3 } -2 \left( \frac{ 1 }{ 2 } - \frac{ 2 }{ 3 } \right)$$

Evaluate

$$\frac{4}{3}\approx 1.333333333$$

Solution Steps

Multiply \frac{4}{5} times -\frac{5}{2} by multiplying numerator times numerator and denominator times denominator.

$$4+\frac{4\left(-5\right)}{5\times 2}\times 3+\frac{2}{\frac{2}{3}}-2\left(\frac{1}{2}-\frac{2}{3}\right)$$

Do the multiplications in the fraction \frac{4\left(-5\right)}{5\times 2}.

$$4+\frac{-20}{10}\times 3+\frac{2}{\frac{2}{3}}-2\left(\frac{1}{2}-\frac{2}{3}\right)$$

Divide -20 by 10 to get -2.

$$4-2\times 3+\frac{2}{\frac{2}{3}}-2\left(\frac{1}{2}-\frac{2}{3}\right)$$

Multiply -2 and 3 to get -6.

$$4-6+\frac{2}{\frac{2}{3}}-2\left(\frac{1}{2}-\frac{2}{3}\right)$$

Subtract 6 from 4 to get -2.

$$-2+\frac{2}{\frac{2}{3}}-2\left(\frac{1}{2}-\frac{2}{3}\right)$$

Divide 2 by \frac{2}{3} by multiplying 2 by the reciprocal of \frac{2}{3}.

$$-2+2\times \frac{3}{2}-2\left(\frac{1}{2}-\frac{2}{3}\right)$$

Cancel out 2 and 2.

$$-2+3-2\left(\frac{1}{2}-\frac{2}{3}\right)$$

Add -2 and 3 to get 1.

$$1-2\left(\frac{1}{2}-\frac{2}{3}\right)$$

Least common multiple of 2 and 3 is 6. Convert \frac{1}{2} and \frac{2}{3} to fractions with denominator 6.

$$1-2\left(\frac{3}{6}-\frac{4}{6}\right)$$

Since \frac{3}{6} and \frac{4}{6} have the same denominator, subtract them by subtracting their numerators.

$$1-2\times \frac{3-4}{6}$$

Subtract 4 from 3 to get -1.

$$1-2\left(-\frac{1}{6}\right)$$

Express 2\left(-\frac{1}{6}\right) as a single fraction.

$$1-\frac{2\left(-1\right)}{6}$$

Multiply 2 and -1 to get -2.

$$1-\frac{-2}{6}$$

Reduce the fraction \frac{-2}{6} to lowest terms by extracting and canceling out 2.

$$1-\left(-\frac{1}{3}\right)$$

The opposite of -\frac{1}{3} is \frac{1}{3}.

$$1+\frac{1}{3}$$

Convert 1 to fraction \frac{3}{3}.

$$\frac{3}{3}+\frac{1}{3}$$

Since \frac{3}{3} and \frac{1}{3} have the same denominator, add them by adding their numerators.

$$\frac{3+1}{3}$$

Add 3 and 1 to get 4.

$$\frac{4}{3}$$

Factor

$$\frac{2 ^ {2}}{3} = 1\frac{1}{3} = 1.3333333333333333$$
