$$1-20 \times \frac{ 1 }{ -15 }$$

Evaluate

$$\frac{7}{3}\approx 2.333333333$$

Solution Steps

Fraction \frac{1}{-15} can be rewritten as -\frac{1}{15} by extracting the negative sign.

$$1-20\left(-\frac{1}{15}\right)$$

Express 20\left(-\frac{1}{15}\right) as a single fraction.

$$1-\frac{20\left(-1\right)}{15}$$

Multiply 20 and -1 to get -20.

$$1-\frac{-20}{15}$$

Reduce the fraction \frac{-20}{15} to lowest terms by extracting and canceling out 5.

$$1-\left(-\frac{4}{3}\right)$$

The opposite of -\frac{4}{3} is \frac{4}{3}.

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

Convert 1 to fraction \frac{3}{3}.

$$\frac{3}{3}+\frac{4}{3}$$

Since \frac{3}{3} and \frac{4}{3} have the same denominator, add them by adding their numerators.

$$\frac{3+4}{3}$$

Add 3 and 4 to get 7.

$$\frac{7}{3}$$

Factor

$$\frac{7}{3} = 2\frac{1}{3} = 2.3333333333333335$$
