Solve 11/2+34/5

$$1 \frac{ 1 }{ 2 } +3 \frac{ 4 }{ 5 }$$

Evaluate

$$\frac{53}{10}=5.3$$

Solution Steps

Multiply 1 and 2 to get 2.

$$\frac{2+1}{2}+\frac{3\times 5+4}{5}$$

Add 2 and 1 to get 3.

$$\frac{3}{2}+\frac{3\times 5+4}{5}$$

Multiply 3 and 5 to get 15.

$$\frac{3}{2}+\frac{15+4}{5}$$

Add 15 and 4 to get 19.

$$\frac{3}{2}+\frac{19}{5}$$

Least common multiple of 2 and 5 is 10. Convert \frac{3}{2} and \frac{19}{5} to fractions with denominator 10.

$$\frac{15}{10}+\frac{38}{10}$$

Since \frac{15}{10} and \frac{38}{10} have the same denominator, add them by adding their numerators.

$$\frac{15+38}{10}$$

Add 15 and 38 to get 53.

$$\frac{53}{10}$$

Factor

$$\frac{53}{2 \cdot 5} = 5\frac{3}{10} = 5.3$$
