\(\frac{37}{6}=6\frac{1}{6}\)
\(\frac{12}{5}=2\frac{2}{5}\)
\(\frac{108}{9}=\frac{12}{1}\)
\(2\dfrac{3}{4}=\dfrac{2\times4+3}{4}=\dfrac{11}{4}\\ 3\dfrac{4}{5}=\dfrac{3\times5+4}{5}=\dfrac{19}{5}\\ 4\dfrac{3}{5}=\dfrac{4\times5+3}{5}=\dfrac{23}{5}\\ 11\dfrac{12}{13}=\dfrac{11\times13+12}{13}=\dfrac{155}{13}\\ 12\dfrac{11}{13}=\dfrac{12\times13+11}{13}=\dfrac{167}{13}\\ 3\dfrac{3}{5}=\dfrac{3\times5+3}{5}=\dfrac{18}{5}\)
2\(\dfrac{3}{4}\)=\(\dfrac{11}{4}\)
3\(\dfrac{4}{5}\)=\(\dfrac{19}{5}\)
4\(\dfrac{3}{5}\)=\(\dfrac{23}{5}\)
11\(\dfrac{12}{13}\)=\(\dfrac{155}{13}\)
12\(\dfrac{11}{13}\)=\(\dfrac{167}{13}\)
3\(\dfrac{3}{5}\)=\(\dfrac{18}{5}\).
\(1\dfrac{1}{5}+1\dfrac{2}{4}=\dfrac{6}{5}+\dfrac{6}{4}=\dfrac{24}{20}+\dfrac{30}{20}=\dfrac{54}{40}\)
Cách chuyển hỗn số thành phân số :
\(1\dfrac{1}{5}=\dfrac{1x5+1}{5}=\dfrac{6}{5}\)
\(1\dfrac{2}{4}=\dfrac{1x4+2}{4}\dfrac{6}{4}\)
4\(\dfrac{1}{2}\)=4,5 3\(\dfrac{4}{5}\)=3,8 2\(\dfrac{3}{4}\)=2,75 1\(\dfrac{12}{25}\)=1,48.
4 1/2=4,5
3 4/5=3,8
2 3/4=2,75
1 12/25=1,48
đúng 100% nha
\(\dfrac{54}{10}=5,4\)
\(4\dfrac{78}{1000}=4+\dfrac{78}{1000}=4+0,078=4,078\)
\(18\dfrac{4}{100}=18+\dfrac{4}{100}=18+0,04=18,04\)
\(\dfrac{1990}{10000}=\dfrac{199}{1000}=0,199\)
\(\dfrac{54}{10}=\dfrac{27}{5}=5,4\)
\(4\dfrac{78}{1000}=\dfrac{39}{125}=0,312\)
\(18\dfrac{4}{100}=\dfrac{18}{25}=0,72\)
\(\dfrac{1990}{10000}=\dfrac{199}{1000}=0,199\)
`12/5 =` `2``2/5`
``37/6 =` `6``1/6`
`108/9 =` `12``0/9`
