Solve 121/3-102/3

$$12 \frac { 1 } { 3 } - 10 \frac { 2 } { 3 }$$

Evaluate

$$\frac{5}{3}\approx 1.666666667$$

Solution Steps

Multiply 12 and 3 to get 36.

$$\frac{36+1}{3}-\frac{10\times 3+2}{3}$$

Add 36 and 1 to get 37.

$$\frac{37}{3}-\frac{10\times 3+2}{3}$$

Multiply 10 and 3 to get 30.

$$\frac{37}{3}-\frac{30+2}{3}$$

Add 30 and 2 to get 32.

$$\frac{37}{3}-\frac{32}{3}$$

Since \frac{37}{3} and \frac{32}{3} have the same denominator, subtract them by subtracting their numerators.

$$\frac{37-32}{3}$$

Subtract 32 from 37 to get 5.

$$\frac{5}{3}$$

Factor

$$\frac{5}{3} = 1\frac{2}{3} = 1.6666666666666667$$
