Question

Solve the equation: 5/6 = 1/3 + D

Answer 1

Answer: $\frac{1}{2}$ 
 
Explanation:
$\frac{5}{6} = \frac{1}{3} + D$ 
$\frac{5}{6} - \frac{1}{3} = \frac{1}{3} - \frac{1}{3} + D$ 
$\frac{5}{6} - \frac{1}{3} = D$ 
$\frac{5}{6} - 2(\frac{1}{3}) = D$
$\frac{5}{6} - \frac{2}{6} = D$ 
$\frac{3}{6} = D$ = $\frac{1}{2}$
