Solve -25/13+72/13

$$-2 \frac{ 5 }{ 13 } +7 \frac{ 2 }{ 13 }$$

Evaluate

$$\frac{62}{13}\approx 4.769230769$$

Solution Steps

Multiply 2 and 13 to get 26.

$$-\frac{26+5}{13}+\frac{7\times 13+2}{13}$$

Add 26 and 5 to get 31.

$$-\frac{31}{13}+\frac{7\times 13+2}{13}$$

Multiply 7 and 13 to get 91.

$$-\frac{31}{13}+\frac{91+2}{13}$$

Add 91 and 2 to get 93.

$$-\frac{31}{13}+\frac{93}{13}$$

Since -\frac{31}{13} and \frac{93}{13} have the same denominator, add them by adding their numerators.

$$\frac{-31+93}{13}$$

Add -31 and 93 to get 62.

$$\frac{62}{13}$$

Factor

$$\frac{2 \cdot 31}{13} = 4\frac{10}{13} = 4.769230769230769$$
