Solve 21/13+38/13

$$2 \frac { 1 } { 13 } + 3 \frac { 8 } { 13 }$$

Evaluate

$$\frac{74}{13}\approx 5.692307692$$

Solution Steps

Multiply 2 and 13 to get 26.

$$\frac{26+1}{13}+\frac{3\times 13+8}{13}$$

Add 26 and 1 to get 27.

$$\frac{27}{13}+\frac{3\times 13+8}{13}$$

Multiply 3 and 13 to get 39.

$$\frac{27}{13}+\frac{39+8}{13}$$

Add 39 and 8 to get 47.

$$\frac{27}{13}+\frac{47}{13}$$

Since \frac{27}{13} and \frac{47}{13} have the same denominator, add them by adding their numerators.

$$\frac{27+47}{13}$$

Add 27 and 47 to get 74.

$$\frac{74}{13}$$

Factor

$$\frac{2 \cdot 37}{13} = 5\frac{9}{13} = 5.6923076923076925$$
