Solve -21/4-13/4

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

Evaluate

$$-4$$

Solution Steps

Multiply 2 and 4 to get 8.

$$-\frac{8+1}{4}-\frac{1\times 4+3}{4}$$

Add 8 and 1 to get 9.

$$-\frac{9}{4}-\frac{1\times 4+3}{4}$$

Multiply 1 and 4 to get 4.

$$-\frac{9}{4}-\frac{4+3}{4}$$

Add 4 and 3 to get 7.

$$-\frac{9}{4}-\frac{7}{4}$$

Since -\frac{9}{4} and \frac{7}{4} have the same denominator, subtract them by subtracting their numerators.

$$\frac{-9-7}{4}$$

Subtract 7 from -9 to get -16.

$$\frac{-16}{4}$$

Divide -16 by 4 to get -4.

$$-4$$

Factor

$$-4$$
