Solve 3.5div1.75+60%-5/2

$$3.5 \div 1.75+60 \% - \frac{ 5 }{ 2 }$$

Evaluate

$$0.1$$

Solution Steps

Expand \frac{3.5}{1.75} by multiplying both numerator and the denominator by 100.

$$\frac{350}{175}+\frac{60}{100}-\frac{5}{2}$$

Divide 350 by 175 to get 2.

$$2+\frac{60}{100}-\frac{5}{2}$$

Reduce the fraction \frac{60}{100} to lowest terms by extracting and canceling out 20.

$$2+\frac{3}{5}-\frac{5}{2}$$

Convert 2 to fraction \frac{10}{5}.

$$\frac{10}{5}+\frac{3}{5}-\frac{5}{2}$$

Since \frac{10}{5} and \frac{3}{5} have the same denominator, add them by adding their numerators.

$$\frac{10+3}{5}-\frac{5}{2}$$

Add 10 and 3 to get 13.

$$\frac{13}{5}-\frac{5}{2}$$

Least common multiple of 5 and 2 is 10. Convert \frac{13}{5} and \frac{5}{2} to fractions with denominator 10.

$$\frac{26}{10}-\frac{25}{10}$$

Since \frac{26}{10} and \frac{25}{10} have the same denominator, subtract them by subtracting their numerators.

$$\frac{26-25}{10}$$

Subtract 25 from 26 to get 1.

$$\frac{1}{10}$$

Factor

$$\frac{1}{2 \cdot 5} = 0.1$$
