X/VIII + VII/ VIII = ...............

Answer 1

\(\frac{4}{5}+\frac{8}{5}=\frac{4+8}{5}=\frac{12}{5}\)

\(\frac{5}{4}+\frac{10}{4}=\frac{5+10}{4}=\frac{15}{4}\)

\(\frac{10}{8}+\frac{7}{8}=\frac{10+7}{8}=\frac{17}{8}\)

Answer 2

IV/V+VIII/V=XII/V

V/VI+X/VI=V/II

X/VIII+VII/VIII=XVII/VIII

Answer 3

4/5 + 8/5 = 12/5

5/6 + 10/6 = 15/6

10/8 + 7/8 = 17/8

Answer 4

IV/V + VIII/V = \(\frac{4}{5}\) + \(\frac{8}{5}\) = \(\frac{4+8}{5}\) = \(\frac{12}{5}\) 

V/VI + X/VI = \(\frac{5}{6}\) + \(\frac{9}{6}\) = \(\frac{5+10}{6}\) \(\frac{15}{6}\)

X/VIII + VII/VIII = \(\frac{9}{8}\) +\(\frac{7}{8}\) =\(\frac{10+7}{8}\) =\(\frac{17}{8}\)

Answer 5

câu 1:12/5
