\(\frac{31}{4}=7\frac{3}{4}\)
\(\frac{25}{3}=8\frac{1}{3}\)
\(\frac{36}{5}=7\frac{1}{5}\)
\(\frac{78}{21}=3\frac{5}{7}\)
\(\frac{65}{23}=2\frac{19}{23}\)
5\(\frac{3}{5}\)= \(\frac{28}{5}\)
4\(\frac{2}{3}\)= \(\frac{14}{3}\)
6\(\frac{6}{7}\)= \(\frac{48}{7}\)
\(5\frac{3}{5}=5.6\) \(4\frac{2}{3}=4\left(6\right)\) \(6\frac{5}{7}=6\left(714285\right)\)
\(\left(a\right)3\frac{2}{4}=3x4+2=\frac{14}{4}\)
\(\left(b\right)5\frac{3}{2}=5x3+2=\frac{17}{2}\)
\(2\dfrac{3}{4}=\dfrac{2\times4+3}{4}=\dfrac{11}{4}\\ 3\dfrac{4}{5}=\dfrac{3\times5+4}{5}=\dfrac{19}{5}\\ 4\dfrac{3}{5}=\dfrac{4\times5+3}{5}=\dfrac{23}{5}\\ 11\dfrac{12}{13}=\dfrac{11\times13+12}{13}=\dfrac{155}{13}\\ 12\dfrac{11}{13}=\dfrac{12\times13+11}{13}=\dfrac{167}{13}\\ 3\dfrac{3}{5}=\dfrac{3\times5+3}{5}=\dfrac{18}{5}\)
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 4/35 + 3 4/7 * 3 1/5 = 39/35 + 25/7 * 16/5 = 39/35 + 80/7 = 39/35 + 400/35 = 439/35
\(1\dfrac{4}{35}+3\dfrac{4}{7}\times3\dfrac{1}{5}=\dfrac{39}{35}+\dfrac{25}{7}\times\dfrac{16}{5}=\dfrac{39}{35}+\dfrac{80}{7}=\dfrac{39}{35}+\dfrac{400}{35}=\dfrac{39+400}{35}=\dfrac{439}{35}\)
1. Mik viết lần lượt là : XII; XLVII; LIV; C; M.
2. \(4\frac{1}{5}=\frac{42}{10}\)
3. 0,2 = 20%; 0,75 = 75%; 0,1 = 10%.
1. XII , XLVII , LIV , C , M
2. \(4\frac{1}{5}=\frac{21}{5}\)
3. 0,2 = 20% , 0,75 = 75%
0,1 = 10 %
=\(\frac{19}{5}\)
\(3\frac{4}{5}=\frac{19}{5}\)
