Solve 1*23/5+171/10=

$$1 \cdot 2 \frac { 3 } { 5 } + 17 \frac { 1 } { 10 } =$$

Evaluate

$$\frac{197}{10}=19.7$$

Solution Steps

Multiply 2 and 5 to get 10.

$$1\times \frac{10+3}{5}+\frac{17\times 10+1}{10}$$

Add 10 and 3 to get 13.

$$1\times \frac{13}{5}+\frac{17\times 10+1}{10}$$

Multiply 1 and \frac{13}{5} to get \frac{13}{5}.

$$\frac{13}{5}+\frac{17\times 10+1}{10}$$

Multiply 17 and 10 to get 170.

$$\frac{13}{5}+\frac{170+1}{10}$$

Add 170 and 1 to get 171.

$$\frac{13}{5}+\frac{171}{10}$$

Least common multiple of 5 and 10 is 10. Convert \frac{13}{5} and \frac{171}{10} to fractions with denominator 10.

$$\frac{26}{10}+\frac{171}{10}$$
