a)5/24<5+10/24>5/8 và 5/24<5/8

b)4/9<6+9/6.9>2/3 và 4/9<2/3

Tính chi giết giúp mình nhé

a)5/24<5+10/24=15/24=5/8 

=>5/24<10/24<5/8

b)2/3>4/9>6+9/6*9=15/54=5/18

=>2/3>4/9>6+9/6*9

\(a.\frac{5}{24}<\frac{5+10}{24}=\frac{15}{24}=\frac{5}{8}\)

\(b.\frac{2}{3}>\frac{4}{9}>\frac{6+9}{6.9}=\frac{15}{54}=\frac{5}{18}\)

a: \(\dfrac{5}{24}< \dfrac{15}{24}=\dfrac{5}{8}\)

b: \(\dfrac{6+9}{6\cdot9}=\dfrac{15}{54}\)

4/9=24/54

2/3=36/54

Do đó: \(\dfrac{15}{54}< \dfrac{24}{54}< \dfrac{36}{54}\)

\(\dfrac{11}{10}< \dfrac{9}{30}\)

\(\dfrac{6}{7}>\dfrac{3}{5}\)

\(\dfrac{25}{100}< \dfrac{3}{4}\)

a \(\dfrac{11}{10}>\dfrac{3}{10}\)

b \(\dfrac{30}{35}>\dfrac{21}{35}\)

c \(\dfrac{1}{4}< \dfrac{3}{4}\)

a, \(\dfrac{11}{10}< \dfrac{9}{30}\)

b, \(\dfrac{6}{7}>\dfrac{3}{5}\)

c, \(\dfrac{25}{100}< \dfrac{3}{4}\)

a)

 \(\dfrac{5}{9}< \dfrac{9}{9}\)

\(\dfrac{8}{7}>\dfrac{7}{7}\)

\(\dfrac{9}{9}=1\)

\(\dfrac{18}{4}>\dfrac{3}{4}\)

b) 

\(\dfrac{2}{5},\dfrac{3}{5},\dfrac{8}{5}\)

\(\dfrac{5}{2}=\dfrac{15}{6},\dfrac{1}{6},1=\dfrac{6}{6}\rightarrow\dfrac{1}{6},\dfrac{6}{6},\dfrac{15}{6}\)

a) \(\dfrac{3}{4}=\dfrac{3x4}{4x4}=\dfrac{12}{16},\dfrac{6}{7}=\dfrac{6x2}{7x2}=\dfrac{12}{14}\)

Do 16 > 14 => \(\dfrac{12}{16}< \dfrac{12}{14}hay\dfrac{3}{4}< \dfrac{6}{7}\)

1216<1214hay34<67
