Solve 1,2:0,6*(0,5-0,4)+0,3*0,2:0,1

$$1,2 : 0,6 \cdot ( 0,5 - 0,4 ) + 0,3 \cdot 0,2 : 0,1$$

Evaluate

$$0,8$$

Solution Steps

Expand \frac{1,2}{0,6} by multiplying both numerator and the denominator by 10.

$$\frac{12}{6}\left(0,5-0,4\right)+\frac{0,3\times 0,2}{0,1}$$

Divide 12 by 6 to get 2.

$$2\left(0,5-0,4\right)+\frac{0,3\times 0,2}{0,1}$$

Subtract 0,4 from 0,5 to get 0,1.

$$2\times 0,1+\frac{0,3\times 0,2}{0,1}$$

Multiply 2 and 0,1 to get 0,2.

$$0,2+\frac{0,3\times 0,2}{0,1}$$

Multiply 0,3 and 0,2 to get 0,06.

$$0,2+\frac{0,06}{0,1}$$

Expand \frac{0,06}{0,1} by multiplying both numerator and the denominator by 100.

$$0,2+\frac{6}{10}$$

Reduce the fraction \frac{6}{10} to lowest terms by extracting and canceling out 2.

$$0,2+\frac{3}{5}$$

Convert decimal number 0,2 to fraction \frac{2}{10}. Reduce the fraction \frac{2}{10} to lowest terms by extracting and canceling out 2.

$$\frac{1}{5}+\frac{3}{5}$$

Since \frac{1}{5} and \frac{3}{5} have the same denominator, add them by adding their numerators.

$$\frac{1+3}{5}$$

Add 1 and 3 to get 4.

$$\frac{4}{5}$$

Factor

$$\frac{2 ^ {2}}{5} = 0.8$$
