a) 2/5 = 4/10
7/4 = 175/100
18/25 = 72/100
b) 32/80 = 4/10
72/400 = 18/100
425/5000 = 85/1000
\(\frac{2}{5}\)=\(\frac{4}{10}\)
\(\frac{7}{4}\)=\(\frac{175}{100}\)
\(\frac{18}{25}\)=\(\frac{72}{100}\)
\(\frac{32}{80}\)=\(\frac{4}{10}\)
\(\frac{72}{400}\)=\(\frac{18}{100}\)
\(\frac{425}{5000}\)=\(\frac{85}{1000}\)
K nhé?
