Solve 21/5+0,5

$$2 \frac { 1 } { 5 } + 0,5$$

Evaluate

$$2,7$$

Solution Steps

Multiply 2 and 5 to get 10.

$$\frac{10+1}{5}+0,5$$

Add 10 and 1 to get 11.

$$\frac{11}{5}+0,5$$

Convert decimal number 0,5 to fraction \frac{5}{10}. Reduce the fraction \frac{5}{10} to lowest terms by extracting and canceling out 5.

$$\frac{11}{5}+\frac{1}{2}$$

Least common multiple of 5 and 2 is 10. Convert \frac{11}{5} and \frac{1}{2} to fractions with denominator 10.

$$\frac{22}{10}+\frac{5}{10}$$

Since \frac{22}{10} and \frac{5}{10} have the same denominator, add them by adding their numerators.

$$\frac{22+5}{10}$$

Add 22 and 5 to get 27.

$$\frac{27}{10}$$

Factor

$$\frac{3 ^ {3}}{2 \cdot 5} = 2\frac{7}{10} = 2.7$$
