Solve 1-3/4+5/18

$$1 - \frac { 3 } { 4 } + \frac { 5 } { 18 }$$

Evaluate

$$\frac{19}{36}\approx 0.527777778$$

Solution Steps

Convert 1 to fraction \frac{4}{4}.

$$\frac{4}{4}-\frac{3}{4}+\frac{5}{18}$$

Since \frac{4}{4} and \frac{3}{4} have the same denominator, subtract them by subtracting their numerators.

$$\frac{4-3}{4}+\frac{5}{18}$$

Subtract 3 from 4 to get 1.

$$\frac{1}{4}+\frac{5}{18}$$

Least common multiple of 4 and 18 is 36. Convert \frac{1}{4} and \frac{5}{18} to fractions with denominator 36.

$$\frac{9}{36}+\frac{10}{36}$$

Since \frac{9}{36} and \frac{10}{36} have the same denominator, add them by adding their numerators.

$$\frac{9+10}{36}$$

Add 9 and 10 to get 19.

$$\frac{19}{36}$$

Factor

$$\frac{19}{2 ^ {2} \cdot 3 ^ {2}} = 0.5277777777777778$$
