3/8-11/16

Let's evaluate: $\frac{3}{8}-\frac{11}{16}$

ⓘ Add fractions by using a common denominator and then adding their numerators. We choose $16$, the least common multiple of $8$ and $16$. Multiplying the numerator and the denominator by the same number does not change the fraction: $\frac{3}{8}-\frac{11}{16}$ = $\frac{3\times 2}{8\times 2}-\frac{11}{16}$ = $\frac{3\times 2-11}{16}$

$\frac{3\times 2-11}{16}$

ⓘ Multiplications are done before additions and subtractions: $3\times 2$ = $6$

$\frac{6-11}{16}$

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

▶Result:   $-\frac{5}{16}$

The numeric value of: $-\frac{5}{16}$ is:

▷ $-0.3125$
