Solve 3+7*2-6,85+6/40+3/30

$$3 + 7 \cdot 2 - 6,85 + \frac { 6 } { 40 } + \frac { 3 } { 30 }$$

Evaluate

$$10,4$$

Solution Steps

Multiply 7 and 2 to get 14.

$$3+14-6,85+\frac{6}{40}+\frac{3}{30}$$

Add 3 and 14 to get 17.

$$17-6,85+\frac{6}{40}+\frac{3}{30}$$

Subtract 6,85 from 17 to get 10,15.

$$10,15+\frac{6}{40}+\frac{3}{30}$$

Reduce the fraction \frac{6}{40} to lowest terms by extracting and canceling out 2.

$$10,15+\frac{3}{20}+\frac{3}{30}$$

Convert decimal number 10,15 to fraction \frac{1015}{100}. Reduce the fraction \frac{1015}{100} to lowest terms by extracting and canceling out 5.

$$\frac{203}{20}+\frac{3}{20}+\frac{3}{30}$$

Since \frac{203}{20} and \frac{3}{20} have the same denominator, add them by adding their numerators.

$$\frac{203+3}{20}+\frac{3}{30}$$

Add 203 and 3 to get 206.

$$\frac{206}{20}+\frac{3}{30}$$

Reduce the fraction \frac{206}{20} to lowest terms by extracting and canceling out 2.

$$\frac{103}{10}+\frac{3}{30}$$

Reduce the fraction \frac{3}{30} to lowest terms by extracting and canceling out 3.

$$\frac{103}{10}+\frac{1}{10}$$

Since \frac{103}{10} and \frac{1}{10} have the same denominator, add them by adding their numerators.

$$\frac{103+1}{10}$$

Add 103 and 1 to get 104.

$$\frac{104}{10}$$

Reduce the fraction \frac{104}{10} to lowest terms by extracting and canceling out 2.

$$\frac{52}{5}$$

Factor

$$\frac{13 \cdot 2 ^ {2}}{5} = 10\frac{2}{5} = 10.4$$
