$$\frac { 71 } { 80 } + 2 - 4$$

Evaluate

$$-\frac{89}{80}=-1.1125$$

Solution Steps

Convert 2 to fraction \frac{160}{80}.

$$\frac{71}{80}+\frac{160}{80}-4$$

Since \frac{71}{80} and \frac{160}{80} have the same denominator, add them by adding their numerators.

$$\frac{71+160}{80}-4$$

Add 71 and 160 to get 231.

$$\frac{231}{80}-4$$

Convert 4 to fraction \frac{320}{80}.

$$\frac{231}{80}-\frac{320}{80}$$

Since \frac{231}{80} and \frac{320}{80} have the same denominator, subtract them by subtracting their numerators.

$$\frac{231-320}{80}$$

Subtract 320 from 231 to get -89.

$$-\frac{89}{80}$$

Factor

$$-\frac{89}{80} = -1\frac{9}{80} = -1.1125$$
