a)\(\dfrac{1}{3}\),\(\dfrac{3}{5}\),\(\dfrac{5}{7}\),\(\dfrac{7}{9}\),\(\dfrac{9}{11}\)

a)-18,-7/9.-2/9,11

b)-17/40;-4/15,-2/5,17

Chẳng hiểu sao dễ thế này lại hỏi nhỉ :)?

7,08; 7,11; 7,5; 7,503

6,12; 6,4; 6,9; 6,98

Với cả hôm nay là chủ nhật mà =) gì mà gấp vậy

a, 7,08 , 7,11 , 7,5 , 7,503 

b) 6,12 ; 6,4 ; 6,9 ; 6,98

Bài 1:

\(a.-5;-3;-2;0;1;2;4\)

\(b.-36;-8;-6;-5;-4;0;6;8;12;15\)

\(c.-129;-98;0;3;27;35\)

Bài 2:

\(a.15;14;9;0;-3;-7;-16\)

\(b.100;17;5;0;-1;-2;-3;-13;-99\)

\(a,\dfrac{-8}{-3};0;\dfrac{-2}{9};\dfrac{-7}{5};\dfrac{-13}{2}\\ b,\dfrac{-13}{-6};\dfrac{-18}{-24};\dfrac{17}{30}\dfrac{-2}{5};\dfrac{-11}{20};\dfrac{-7}{12}\)

a) -12,13; -2,4; -2,3; 0,5; 2,4

b) 2,999; 2,9; -2,9; -2,999

a) -12,13; -2,4; -2,3; 0,5; 2,4

b) 2,999; 2,9; -2,9; -2,999

a) -12,13; -2,4; -2,3; 0,5; 2,4

b) 2,999; 2,9; -2,9; -2,999

Ta có: \(\frac{-3}{5}=\frac{-3\cdot16}{5\cdot16}=\frac{-48}{80};\frac{4}{-8}=\frac{-4}{8}=\frac{-4\cdot10}{8\cdot10}=\frac{-40}{80}\)

\(\frac54=\frac{5\cdot20}{4\cdot20}=\frac{100}{80};\frac{3}{-10}=\frac{-3}{10}=\frac{-3\cdot8}{10\cdot8}=-\frac{24}{80}\) ;

\(\frac{-12}{30}=\frac{-12:6}{30:6}=\frac{-2}{5}=\frac{-2\cdot16}{5\cdot16}=\frac{-32}{80}\)

\(\frac32=\frac{3\cdot40}{2\cdot40}=\frac{120}{80}\)

mà \(-\frac{48}{80}<-\frac{40}{80}<-\frac{32}{80}<-\frac{24}{80}<\frac{100}{80}<\frac{120}{80}\)

nên \(-\frac35<-\frac12<-\frac25<\frac{3}{-10}<\frac54<\frac32\)
