Solve 303/7-92/7

$$30 \frac { 3 } { 7 } - 9 \frac { 2 } { 7 }$$

Evaluate

$$\frac{148}{7}\approx 21.142857143$$

Solution Steps

Multiply 30 and 7 to get 210.

$$\frac{210+3}{7}-\frac{9\times 7+2}{7}$$

Add 210 and 3 to get 213.

$$\frac{213}{7}-\frac{9\times 7+2}{7}$$

Multiply 9 and 7 to get 63.

$$\frac{213}{7}-\frac{63+2}{7}$$

Add 63 and 2 to get 65.

$$\frac{213}{7}-\frac{65}{7}$$

Since \frac{213}{7} and \frac{65}{7} have the same denominator, subtract them by subtracting their numerators.

$$\frac{213-65}{7}$$

Subtract 65 from 213 to get 148.

$$\frac{148}{7}$$

Factor

$$\frac{2 ^ {2} \cdot 37}{7} = 21\frac{1}{7} = 21.142857142857142$$
