a, \(\frac{4.7}{9.32}\)= \(\frac{7}{9.8}\)=\(\frac{7}{72}\)
b. \(\frac{3.21}{14.15}\)= \(\frac{21}{14.5}\)= \(\frac{3}{2.5}\)= \(\frac{3}{10}\)
\(a,\frac{4.7}{9.32}=\frac{4.7}{9.4.8}=\frac{7}{9.8}=\frac{7}{72}\)
\(b,\frac{3.21}{14.15}=\frac{3.21}{2.7.3.5}=\frac{3.21}{2.21.5}=\frac{3}{2.5}=\frac{3}{10}\)
\(c,\frac{2.5.13}{26.35}=\frac{2.5.13}{13.2.7.5}=\frac{1}{7}\)
c, \(\frac{2.5.13}{26.35}\)= \(\frac{2.13}{26.7}\)= \(\frac{2}{2.7}\)= \(\frac{2}{14}\)
