= chín phần hai
1/3 + 5/2 + 10/6 = 4/12 + 30/12 + 20/12 = 54/12 = 27/6
1/3 + 5/2 + 10/6 =
Quy đồng :
1/3 = 1/3 x 2 = 2/6
5/2 = 5/2 x 3 = 15/6
10/6 giữ nguyên
=> 2/6 + 15/6 + 10/6 = 27/6
Vậy : 1/3 + 5/2 + 10/6 = 27/6
\(\frac{1}{3}+\frac{5}{2}+\frac{10}{6}\)
\(=\frac{1}{3}+\frac{5}{2}+\frac{5}{3}\)
\(=\frac{4}{12}+\frac{30}{12}+\frac{20}{12}\)
\(=\frac{54}{12}=\frac{9}{2}\)
