Solve -3/4-11/10

$$- \frac { 3 } { 4 } - 1 \frac { 1 } { 10 }$$

Evaluate

$$-\frac{37}{20}=-1.85$$

Solution Steps

Multiply 1 and 10 to get 10.

$$-\frac{3}{4}-\frac{10+1}{10}$$

Add 10 and 1 to get 11.

$$-\frac{3}{4}-\frac{11}{10}$$

Least common multiple of 4 and 10 is 20. Convert -\frac{3}{4} and \frac{11}{10} to fractions with denominator 20.

$$-\frac{15}{20}-\frac{22}{20}$$

Since -\frac{15}{20} and \frac{22}{20} have the same denominator, subtract them by subtracting their numerators.

$$\frac{-15-22}{20}$$

Subtract 22 from -15 to get -37.

$$-\frac{37}{20}$$

Factor

$$-\frac{37}{20} = -1\frac{17}{20} = -1.85$$
