Evaluate

$$\frac{6964}{175}\approx 39.794285714$$

Solution Steps

Express \frac{\frac{18}{7}}{100} as a single fraction.

$$12+2\left(-\frac{18}{7\times 100}\right)\times 4+7\times 4$$

Multiply 7 and 100 to get 700.

$$12+2\left(-\frac{18}{700}\right)\times 4+7\times 4$$

Reduce the fraction \frac{18}{700} to lowest terms by extracting and canceling out 2.

$$12+2\left(-\frac{9}{350}\right)\times 4+7\times 4$$

Express 2\left(-\frac{9}{350}\right) as a single fraction.

$$12+\frac{2\left(-9\right)}{350}\times 4+7\times 4$$

Multiply 2 and -9 to get -18.

$$12+\frac{-18}{350}\times 4+7\times 4$$

Reduce the fraction \frac{-18}{350} to lowest terms by extracting and canceling out 2.

$$12-\frac{9}{175}\times 4+7\times 4$$

Express -\frac{9}{175}\times 4 as a single fraction.

$$12+\frac{-9\times 4}{175}+7\times 4$$

Multiply -9 and 4 to get -36.

$$12+\frac{-36}{175}+7\times 4$$

Fraction \frac{-36}{175} can be rewritten as -\frac{36}{175} by extracting the negative sign.

$$12-\frac{36}{175}+7\times 4$$

Convert 12 to fraction \frac{2100}{175}.

$$\frac{2100}{175}-\frac{36}{175}+7\times 4$$

Since \frac{2100}{175} and \frac{36}{175} have the same denominator, subtract them by subtracting their numerators.

$$\frac{2100-36}{175}+7\times 4$$

Subtract 36 from 2100 to get 2064.

$$\frac{2064}{175}+7\times 4$$

Multiply 7 and 4 to get 28.

$$\frac{2064}{175}+28$$

Convert 28 to fraction \frac{4900}{175}.

$$\frac{2064}{175}+\frac{4900}{175}$$

Since \frac{2064}{175} and \frac{4900}{175} have the same denominator, add them by adding their numerators.

$$\frac{2064+4900}{175}$$

Add 2064 and 4900 to get 6964.

$$\frac{6964}{175}$$

Factor

$$\frac{2 ^ {2} \cdot 1741}{5 ^ {2} \cdot 7} = 39\frac{139}{175} = 39.794285714285714$$
