Đúng ko
K mk nha
a) \(3\frac{2}{7}=\frac{3.7+2}{7}=\frac{23}{7}\) b) \(2\frac{5}{12}=\frac{2.12+5}{12}=\frac{29}{12}\)
c) \(9\frac{5}{9}=\frac{9.9+5}{9}=\frac{86}{9}\) d) \(12\frac{3}{4}=\frac{12.4+3}{4}=\frac{51}{4}\)
a . \(3\frac{2}{7}=\frac{3\cdot7+2}{7}=\frac{23}{7}\)
b . \(2\frac{5}{12}=\frac{2\cdot12+5}{12}\frac{29}{12}\)
c . \(9\frac{5}{9}=\frac{9\cdot9+5}{9}=\frac{86}{9}\)
d . \(12\frac{3}{4}=\frac{12\cdot4+3}{4}=\frac{51}{4}\)
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
