Solve 54/5-71/3=

$$5 \frac { 4 } { 5 } - 7 \frac { 1 } { 3 } =$$

Evaluate

$$-\frac{23}{15}\approx -1.533333333$$

Solution Steps

Multiply 5 and 5 to get 25.

$$\frac{25+4}{5}-\frac{7\times 3+1}{3}$$

Add 25 and 4 to get 29.

$$\frac{29}{5}-\frac{7\times 3+1}{3}$$

Multiply 7 and 3 to get 21.

$$\frac{29}{5}-\frac{21+1}{3}$$

Add 21 and 1 to get 22.

$$\frac{29}{5}-\frac{22}{3}$$

Least common multiple of 5 and 3 is 15. Convert \frac{29}{5} and \frac{22}{3} to fractions with denominator 15.

$$\frac{87}{15}-\frac{110}{15}$$

Since \frac{87}{15} and \frac{110}{15} have the same denominator, subtract them by subtracting their numerators.

$$\frac{87-110}{15}$$

Subtract 110 from 87 to get -23.

$$-\frac{23}{15}$$

Factor

$$-\frac{23}{15} = -1\frac{8}{15} = -1.5333333333333334$$
