k mình nhoa ! ~~~
98/25 = 3,92
36/16 = 2,25
18/4 = 4,5
26/5 = 5,2
\(\frac{98}{25}=3,98\) \(\frac{36}{16}=2,25\) \(\frac{18}{4}=4,5\) \(\frac{26}{5}=5,2\)
98/25=3,92
36/16=2,25
18/4=4,5
26/5=5,2
Bài này dễ chỉ cần chịu khó bấm máy tính là ra thôi mà :
\(\frac{98}{25}=3,92\)
\(\frac{36}{16}=2,25\)
\(\frac{18}{4}=4,5\)
\(\frac{26}{5}=5,2\)
98/25 = 3,92
36/16 = 2,25
18/4 = 4,5
26/5 = 5,2
\(\frac{98}{25}=\frac{100}{25}-\frac{2}{25}=4-0,08=3,92\)
\(\frac{36}{16}=\frac{32}{16}+\frac{4}{16}=2+0,25=2,25\)
\(\frac{18}{4}=\frac{16}{4}+\frac{2}{4}=4+0,5=4,5\)
\(\frac{26}{5}=\frac{25}{5}+\frac{1}{5}=5+0,2=5,2\)
