7/16-3/4

Let's calculate: $\frac{7}{16}-\frac{3}{4}$

ⓘ To add fractions, put them over the same denominator, then add the numerators. We choose $16$, the least common multiple of $16$ and $4$. Multiplying the numerator and the denominator by the same number does not change the fraction: $\frac{7}{16}-\frac{3}{4}$ = $\frac{7}{16}-\frac{3\times 4}{4\times 4}$ = $\frac{7-3\times 4}{16}$

$\frac{7-3\times 4}{16}$

ⓘ Multiplications are done before additions and subtractions: $3\times 4$ = $12$

$\frac{7-12}{16}$

ⓘ The numerator and the denominator are computed before the division: $7-12$ = $-5$

▶Result:   $-\frac{5}{16}$

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

▷ $-0.3125$
