Solve 36/7-21/7=

$$3 \frac { 6 } { 7 } - 2 \frac { 1 } { 7 } =$$

Evaluate

$$\frac{12}{7}\approx 1.714285714$$

Solution Steps

Multiply 3 and 7 to get 21.

$$\frac{21+6}{7}-\frac{2\times 7+1}{7}$$

Add 21 and 6 to get 27.

$$\frac{27}{7}-\frac{2\times 7+1}{7}$$

Multiply 2 and 7 to get 14.

$$\frac{27}{7}-\frac{14+1}{7}$$

Add 14 and 1 to get 15.

$$\frac{27}{7}-\frac{15}{7}$$

Since \frac{27}{7} and \frac{15}{7} have the same denominator, subtract them by subtracting their numerators.

$$\frac{27-15}{7}$$

Subtract 15 from 27 to get 12.

$$\frac{12}{7}$$

Factor

$$\frac{2 ^ {2} \cdot 3}{7} = 1\frac{5}{7} = 1.7142857142857142$$
