Answer:
Step-by-step explanation:
[tex]-\frac{2}{3}a+\frac{5}{6}a-\frac{1}{6}[/tex]
Like term are [tex]-\frac{2}{3}a+\frac{5}{6}a[/tex], LCD of 3 ,6 = 6
[tex]\frac{-2*2}{3*2}a+\frac{5}{6}a-\frac{1}{6}=\frac{-4}{6}a+\frac{5}{6}a-\frac{1}{6}\\\\=\frac{(-4+5)}{6}a-\frac{1}{6}\\\\=\frac{1}{6}a-\frac{1}{6}\\[/tex]
