$$- \frac { 3 } { 5 } + \frac { 1 } { 2 } \times \frac { 3 } { 4 }$$

Evaluate

$$-\frac{9}{40}=-0.225$$

Solution Steps

Multiply \frac{1}{2} times \frac{3}{4} by multiplying numerator times numerator and denominator times denominator.

$$-\frac{3}{5}+\frac{1\times 3}{2\times 4}$$

Do the multiplications in the fraction \frac{1\times 3}{2\times 4}.

$$-\frac{3}{5}+\frac{3}{8}$$

Least common multiple of 5 and 8 is 40. Convert -\frac{3}{5} and \frac{3}{8} to fractions with denominator 40.

$$-\frac{24}{40}+\frac{15}{40}$$
