Solve -21/10-7+2725

$$- 2 \frac { 1 } { 10 } - 7 + 2725$$

Evaluate

$$\frac{27159}{10}=2715.9$$

Solution Steps

Multiply 2 and 10 to get 20.

$$-\frac{20+1}{10}-7+2725$$

Add 20 and 1 to get 21.

$$-\frac{21}{10}-7+2725$$

Convert 7 to fraction \frac{70}{10}.

$$-\frac{21}{10}-\frac{70}{10}+2725$$

Since -\frac{21}{10} and \frac{70}{10} have the same denominator, subtract them by subtracting their numerators.

$$\frac{-21-70}{10}+2725$$

Subtract 70 from -21 to get -91.

$$-\frac{91}{10}+2725$$

Convert 2725 to fraction \frac{27250}{10}.

$$-\frac{91}{10}+\frac{27250}{10}$$

Since -\frac{91}{10} and \frac{27250}{10} have the same denominator, add them by adding their numerators.

$$\frac{-91+27250}{10}$$

Add -91 and 27250 to get 27159.

$$\frac{27159}{10}$$

Factor

$$\frac{3 \cdot 11 \cdot 823}{2 \cdot 5} = 2715\frac{9}{10} = 2715.9$$
