Solve 22/7-15/7

$$2 \frac { 2 } { 7 } - 1 \frac { 5 } { 7 }$$

Evaluate

$$\frac{4}{7}\approx 0.571428571$$

Solution Steps

Multiply 2 and 7 to get 14.

$$\frac{14+2}{7}-\frac{1\times 7+5}{7}$$

Add 14 and 2 to get 16.

$$\frac{16}{7}-\frac{1\times 7+5}{7}$$

Multiply 1 and 7 to get 7.

$$\frac{16}{7}-\frac{7+5}{7}$$

Add 7 and 5 to get 12.

$$\frac{16}{7}-\frac{12}{7}$$

Since \frac{16}{7} and \frac{12}{7} have the same denominator, subtract them by subtracting their numerators.

$$\frac{16-12}{7}$$

Subtract 12 from 16 to get 4.

$$\frac{4}{7}$$

Factor

$$\frac{2 ^ {2}}{7} = 0.5714285714285714$$
