Ta có:
\(\frac{7}{8}=\frac{1}{8}+\frac{2}{8}+\frac{4}{8}\)
\(\frac{7}{8}=\frac{1}{8}+\frac{1}{4}+\frac{1}{2}\)
Ta có:\(\frac{7}{8}=\frac{1}{8}+\frac{2}{8}+\frac{4}{8}=\frac{1}{8}+\frac{1}{4}+\frac{1}{2}\)
Vậy 7/8 thành 3 phân số tối giản là:1/8+1/4+1/2
7/8 = 1/8+2/8+4/8
7/8 = 1/8+1/4+1/2
7/8 = 5/8+1/8+1/8
