\(\frac{5.1}{3}\)- \(\frac{2.5}{6}\)= \(\frac{77}{60}\)

\(5\frac{1}{3}-2\frac{5}{6}=\frac{16}{3}-\frac{17}{6}=\frac{32}{6}-\frac{17}{6}=\frac{32-17}{6}=\frac{15}{6}\)
51/3 - 25/6
= 5 + 1 /3 + 2 + 5 / 6
= 5 / 1 + 2 / 6 + 2 /1 + 5 / 6
= 5 / 1 + 2 / 1 + 2 / 6 + 5 / 6
7 / 1 + 7 / 6 = 42 / 6 + 7 / 6 = 49 / 6
