Solve 155/7-quad76/7

$$15 \frac { 5 } { 7 } - \quad 7 \frac { 6 } { 7 }$$

Evaluate

$$\frac{55}{7}\approx 7.857142857$$

Solution Steps

Multiply 15 and 7 to get 105.

$$\frac{105+5}{7}-\frac{7\times 7+6}{7}$$

Add 105 and 5 to get 110.

$$\frac{110}{7}-\frac{7\times 7+6}{7}$$

Multiply 7 and 7 to get 49.

$$\frac{110}{7}-\frac{49+6}{7}$$

Add 49 and 6 to get 55.

$$\frac{110}{7}-\frac{55}{7}$$

Since \frac{110}{7} and \frac{55}{7} have the same denominator, subtract them by subtracting their numerators.

$$\frac{110-55}{7}$$

Subtract 55 from 110 to get 55.

$$\frac{55}{7}$$

Factor

$$\frac{5 \cdot 11}{7} = 7\frac{6}{7} = 7.857142857142857$$
