Solve (-12/3-21/3)+2.5

$$(-1 \frac{ 2 }{ 3 } -2 \frac{ 1 }{ 3 } )+2.5$$

Evaluate

$$-1.5$$

Solution Steps

Multiply 1 and 3 to get 3.

$$-\frac{3+2}{3}-\frac{2\times 3+1}{3}+2.5$$

Add 3 and 2 to get 5.

$$-\frac{5}{3}-\frac{2\times 3+1}{3}+2.5$$

Multiply 2 and 3 to get 6.

$$-\frac{5}{3}-\frac{6+1}{3}+2.5$$

Add 6 and 1 to get 7.

$$-\frac{5}{3}-\frac{7}{3}+2.5$$

Since -\frac{5}{3} and \frac{7}{3} have the same denominator, subtract them by subtracting their numerators.

$$\frac{-5-7}{3}+2.5$$

Subtract 7 from -5 to get -12.

$$\frac{-12}{3}+2.5$$

Divide -12 by 3 to get -4.

$$-4+2.5$$

Add -4 and 2.5 to get -1.5.

$$-1.5$$

Factor

$$-1.5$$
