$$1.8-4 \% -3 \% -10 \% -15 \%$$

Evaluate

$$1.48$$

Solution Steps

Reduce the fraction \frac{4}{100} to lowest terms by extracting and canceling out 4.

$$1.8-\frac{1}{25}-\frac{3}{100}-\frac{10}{100}-\frac{15}{100}$$

Convert decimal number 1.8 to fraction \frac{18}{10}. Reduce the fraction \frac{18}{10} to lowest terms by extracting and canceling out 2.

$$\frac{9}{5}-\frac{1}{25}-\frac{3}{100}-\frac{10}{100}-\frac{15}{100}$$

Least common multiple of 5 and 25 is 25. Convert \frac{9}{5} and \frac{1}{25} to fractions with denominator 25.

$$\frac{45}{25}-\frac{1}{25}-\frac{3}{100}-\frac{10}{100}-\frac{15}{100}$$

Since \frac{45}{25} and \frac{1}{25} have the same denominator, subtract them by subtracting their numerators.

$$\frac{45-1}{25}-\frac{3}{100}-\frac{10}{100}-\frac{15}{100}$$

Subtract 1 from 45 to get 44.

$$\frac{44}{25}-\frac{3}{100}-\frac{10}{100}-\frac{15}{100}$$

Least common multiple of 25 and 100 is 100. Convert \frac{44}{25} and \frac{3}{100} to fractions with denominator 100.

$$\frac{176}{100}-\frac{3}{100}-\frac{10}{100}-\frac{15}{100}$$

Since \frac{176}{100} and \frac{3}{100} have the same denominator, subtract them by subtracting their numerators.

$$\frac{176-3}{100}-\frac{10}{100}-\frac{15}{100}$$

Subtract 3 from 176 to get 173.

$$\frac{173}{100}-\frac{10}{100}-\frac{15}{100}$$

Since \frac{173}{100} and \frac{10}{100} have the same denominator, subtract them by subtracting their numerators.

$$\frac{173-10}{100}-\frac{15}{100}$$

Subtract 10 from 173 to get 163.

$$\frac{163}{100}-\frac{15}{100}$$

Since \frac{163}{100} and \frac{15}{100} have the same denominator, subtract them by subtracting their numerators.

$$\frac{163-15}{100}$$

Subtract 15 from 163 to get 148.

$$\frac{148}{100}$$

Reduce the fraction \frac{148}{100} to lowest terms by extracting and canceling out 4.

$$\frac{37}{25}$$

Factor

$$\frac{37}{5 ^ {2}} = 1\frac{12}{25} = 1.48$$
