Solution Steps

Least common multiple of 2 and 5 is 10. Convert -\frac{5}{2} and \frac{3}{5} to fractions with denominator 10.

$$\left(3-\left(-\frac{25}{10}+\frac{6}{10}+\frac{1}{4}\right)\left(-\frac{6}{11}\right)\right)\left(1-\frac{3}{4}-\frac{7}{3}\right)$$

Since -\frac{25}{10} and \frac{6}{10} have the same denominator, add them by adding their numerators.

$$\left(3-\left(\frac{-25+6}{10}+\frac{1}{4}\right)\left(-\frac{6}{11}\right)\right)\left(1-\frac{3}{4}-\frac{7}{3}\right)$$

Add -25 and 6 to get -19.

$$\left(3-\left(-\frac{19}{10}+\frac{1}{4}\right)\left(-\frac{6}{11}\right)\right)\left(1-\frac{3}{4}-\frac{7}{3}\right)$$

Least common multiple of 10 and 4 is 20. Convert -\frac{19}{10} and \frac{1}{4} to fractions with denominator 20.

$$\left(3-\left(-\frac{38}{20}+\frac{5}{20}\right)\left(-\frac{6}{11}\right)\right)\left(1-\frac{3}{4}-\frac{7}{3}\right)$$

Since -\frac{38}{20} and \frac{5}{20} have the same denominator, add them by adding their numerators.

$$\left(3-\frac{-38+5}{20}\left(-\frac{6}{11}\right)\right)\left(1-\frac{3}{4}-\frac{7}{3}\right)$$

Add -38 and 5 to get -33.

$$\left(3-\left(-\frac{33}{20}\left(-\frac{6}{11}\right)\right)\right)\left(1-\frac{3}{4}-\frac{7}{3}\right)$$

Multiply -\frac{33}{20} times -\frac{6}{11} by multiplying numerator times numerator and denominator times denominator.

$$\left(3-\frac{-33\left(-6\right)}{20\times 11}\right)\left(1-\frac{3}{4}-\frac{7}{3}\right)$$

Do the multiplications in the fraction \frac{-33\left(-6\right)}{20\times 11}.

$$\left(3-\frac{198}{220}\right)\left(1-\frac{3}{4}-\frac{7}{3}\right)$$

Reduce the fraction \frac{198}{220} to lowest terms by extracting and canceling out 22.

$$\left(3-\frac{9}{10}\right)\left(1-\frac{3}{4}-\frac{7}{3}\right)$$

Convert 3 to fraction \frac{30}{10}.

$$\left(\frac{30}{10}-\frac{9}{10}\right)\left(1-\frac{3}{4}-\frac{7}{3}\right)$$

Since \frac{30}{10} and \frac{9}{10} have the same denominator, subtract them by subtracting their numerators.

$$\frac{30-9}{10}\left(1-\frac{3}{4}-\frac{7}{3}\right)$$

Subtract 9 from 30 to get 21.

$$\frac{21}{10}\left(1-\frac{3}{4}-\frac{7}{3}\right)$$

Convert 1 to fraction \frac{4}{4}.

$$\frac{21}{10}\left(\frac{4}{4}-\frac{3}{4}-\frac{7}{3}\right)$$

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

$$\frac{21}{10}\left(\frac{4-3}{4}-\frac{7}{3}\right)$$

Subtract 3 from 4 to get 1.

$$\frac{21}{10}\left(\frac{1}{4}-\frac{7}{3}\right)$$

Least common multiple of 4 and 3 is 12. Convert \frac{1}{4} and \frac{7}{3} to fractions with denominator 12.

$$\frac{21}{10}\left(\frac{3}{12}-\frac{28}{12}\right)$$

Since \frac{3}{12} and \frac{28}{12} have the same denominator, subtract them by subtracting their numerators.

$$\frac{21}{10}\times \frac{3-28}{12}$$

Subtract 28 from 3 to get -25.

$$\frac{21}{10}\left(-\frac{25}{12}\right)$$

Multiply \frac{21}{10} times -\frac{25}{12} by multiplying numerator times numerator and denominator times denominator.

$$\frac{21\left(-25\right)}{10\times 12}$$

Do the multiplications in the fraction \frac{21\left(-25\right)}{10\times 12}.

$$\frac{-525}{120}$$

Reduce the fraction \frac{-525}{120} to lowest terms by extracting and canceling out 15.

$$-\frac{35}{8}$$

Factor

$$-\frac{35}{8} = -4\frac{3}{8} = -4.375$$
