1/3-11/18

Let's evaluate: $\frac{1}{3}-\frac{11}{18}$

ⓘ Add fractions by using a common denominator and then adding their numerators. We choose $18$, the least common multiple of $3$ and $18$. Multiplying the numerator and the denominator by the same number does not change the fraction: $\frac{1}{3}-\frac{11}{18}$ = $\frac{1\times 6}{3\times 6}-\frac{11}{18}$ = $\frac{1\times 6-11}{18}$ = $\frac{6-11}{18}$

$\frac{6-11}{18}$

ⓘ The numerator and the denominator are computed before the division: $6-11$ = $-5$

▶Result:   $-\frac{5}{18}$

The numeric value of: $-\frac{5}{18}$ equals:

▷ $\approx -0.2778$
