Solve 72/7+52/7

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

Evaluate

$$\frac{88}{7}\approx 12.571428571$$

Solution Steps

Multiply 7 and 7 to get 49.

$$\frac{49+2}{7}+\frac{5\times 7+2}{7}$$

Add 49 and 2 to get 51.

$$\frac{51}{7}+\frac{5\times 7+2}{7}$$

Multiply 5 and 7 to get 35.

$$\frac{51}{7}+\frac{35+2}{7}$$

Add 35 and 2 to get 37.

$$\frac{51}{7}+\frac{37}{7}$$

Since \frac{51}{7} and \frac{37}{7} have the same denominator, add them by adding their numerators.

$$\frac{51+37}{7}$$

Add 51 and 37 to get 88.

$$\frac{88}{7}$$

Factor

$$\frac{2 ^ {3} \cdot 11}{7} = 12\frac{4}{7} = 12.571428571428571$$
