(-3/2x4/5)+(9/5-10/3)-(1/2x3/4)
Lynna [10]

\left ( \frac{3}{2}\times \frac{4}{5} \right )+\left ( \frac{9}{5}- \frac{10}{3} \right )-\left ( \frac{1}{2}\times \frac{3}{4} \right )

In the first parenthesis, multiply the numerators so we get -12 and after multiply the denominator we will get 10

So the fraction in the first parenthesis will be \left ( \frac{-12}{10} \right )

To solve the 2nd parenethesis, find the LCD of the denominator.

So the LCD of 5 and 3 = 15,

Now make the each denominator same as that of LCD.

So the new fractions in the 2nd parenthesis = (\left ( \frac{27}{15}- \frac{50}{15} \right ) = \left ( \frac{-23}{15} \right )

In the third parenthesis, multiply the numerators so we get 3 and after multiply the denominator we will get 8

So third parenthesis = \left ( \frac{3}{8}\ \right )

= \left ( \frac{-12}{10} \right ) + \left ( \frac{-23}{15} \right ) -\left ( \frac{3}{8}\ \right )

LCD of 12,15 and 8 is 120

=\left ( \frac{-144}{120} \right ) + \left ( \frac{-184}{120} \right ) -\left ( \frac{45}{120}\ \right )

=\left ( \frac{-373}{120} \right )
