$$1 \div -0.75+1 \div 10$$

Evaluate

$$-\frac{37}{30}\approx -1.233333333$$

Solution Steps

Expand \frac{1}{-0.75} by multiplying both numerator and the denominator by 100.

$$\frac{100}{-75}+\frac{1}{10}$$

Reduce the fraction \frac{100}{-75} to lowest terms by extracting and canceling out 25.

$$-\frac{4}{3}+\frac{1}{10}$$

Least common multiple of 3 and 10 is 30. Convert -\frac{4}{3} and \frac{1}{10} to fractions with denominator 30.

$$-\frac{40}{30}+\frac{3}{30}$$

Since -\frac{40}{30} and \frac{3}{30} have the same denominator, add them by adding their numerators.

$$\frac{-40+3}{30}$$

Add -40 and 3 to get -37.

$$-\frac{37}{30}$$

Factor

$$-\frac{37}{30} = -1\frac{7}{30} = -1.2333333333333334$$
