Đáp án :
7/20 = 35/100
9/25 = 36/100
15/125 = 120/1000.
\(\frac{7}{20}\)= \(\frac{35}{100}\)
\(\frac{9}{25}\)= \(\frac{36}{100}\)
\(\frac{15}{125}\)= \(\frac{120}{1000}\)
\(\frac{98}{100}\)= \(\frac{98}{100}\)
\(\frac{15}{150}\)= \(\frac{1}{10}\)
7/20 = 0 ,35
9/25 = 0 ,36
15/125 = 0 ,12
98/100 = 0 ,98
15/150 = 0 , 1
\(\frac{7}{20}=\frac{35}{100}=0,35\)
\(\frac{9}{25}=\frac{36}{100}=0,36\)
\(\frac{15}{125}=\frac{120}{1000}=0,12\)
\(\frac{98}{100}=0,98\)
\(\frac{15}{150}=\frac{5}{50}=\frac{10}{100}=0,1\)
