Solve 0,8*4-0,75:0,25+1,5*0,2-0,4:2

$$0,8 \times 4 - 0,75 : 0,25 + 1,5 \times 0,2 - 0,4 : 2$$

Evaluate

$$0,3$$

Solution Steps

Multiply 0,8 and 4 to get 3,2.

$$3,2-\frac{0,75}{0,25}+1,5\times 0,2-\frac{0,4}{2}$$

Expand \frac{0,75}{0,25} by multiplying both numerator and the denominator by 100.

$$3,2-\frac{75}{25}+1,5\times 0,2-\frac{0,4}{2}$$

Divide 75 by 25 to get 3.

$$3,2-3+1,5\times 0,2-\frac{0,4}{2}$$

Subtract 3 from 3,2 to get 0,2.

$$0,2+1,5\times 0,2-\frac{0,4}{2}$$

Multiply 1,5 and 0,2 to get 0,3.

$$0,2+0,3-\frac{0,4}{2}$$

Add 0,2 and 0,3 to get 0,5.

$$0,5-\frac{0,4}{2}$$

Expand \frac{0,4}{2} by multiplying both numerator and the denominator by 10.

$$0,5-\frac{4}{20}$$

Reduce the fraction \frac{4}{20} to lowest terms by extracting and canceling out 4.

$$0,5-\frac{1}{5}$$

Convert decimal number 0,5 to fraction \frac{5}{10}. Reduce the fraction \frac{5}{10} to lowest terms by extracting and canceling out 5.

$$\frac{1}{2}-\frac{1}{5}$$

Least common multiple of 2 and 5 is 10. Convert \frac{1}{2} and \frac{1}{5} to fractions with denominator 10.

$$\frac{5}{10}-\frac{2}{10}$$

Since \frac{5}{10} and \frac{2}{10} have the same denominator, subtract them by subtracting their numerators.

$$\frac{5-2}{10}$$

Subtract 2 from 5 to get 3.

$$\frac{3}{10}$$

Factor

$$\frac{3}{2 \cdot 5} = 0.3$$
