Solve 1/10-43/10

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

Evaluate

$$-\frac{21}{5}=-4.2$$

Solution Steps

Multiply 4 and 10 to get 40.

$$\frac{1}{10}-\frac{40+3}{10}$$

Add 40 and 3 to get 43.

$$\frac{1}{10}-\frac{43}{10}$$

Since \frac{1}{10} and \frac{43}{10} have the same denominator, subtract them by subtracting their numerators.

$$\frac{1-43}{10}$$

Subtract 43 from 1 to get -42.

$$\frac{-42}{10}$$

Reduce the fraction \frac{-42}{10} to lowest terms by extracting and canceling out 2.

$$-\frac{21}{5}$$

Factor

$$-\frac{21}{5} = -4\frac{1}{5} = -4.2$$
