a)  − 67 50 = − 1 , 34

b)  − 15 60 = 0 , 25

a)  0, 4        

b) 0,75       

c) -3,75     

d) – 15,4

a) Thực hiện rút gọn 8 16 = 1 2 , sau đó quy đồng  1 2 = 5 10

Từ đó ta có 8 16 = 0,5

b ) 33 25 = 1,32. c ) − 67 50 = − 1,34. d ) − 15 60 = 0,25

\(0,03=\dfrac{3}{100}\)

\(0,087=\dfrac{87}{1000}\)

a, \(0,03=\dfrac{3}{100}\)

b, \(0,087=\dfrac{87}{1000}\)

a. \(0,03=\dfrac{3}{100};b.0,087=\dfrac{87}{1000}\)

\(\frac{2}{5}=\frac{4}{10}\)\(\frac{5}{2}=\frac{25}{10}\) \(\frac{16}{25}=\frac{64}{100}\) \(\frac{132}{125}=\frac{1052}{1000}\)

2,5 ; 0,4 ; 2,125 ; 0,64 ; 1,056

\(\frac{5}{2}=\frac{5.5}{2.5}=\frac{25}{10}\)

\(\frac{2}{5}=\frac{2.2}{5.2}=\frac{4}{10}\)

\(\frac{17}{8}=\frac{17.125}{8.125}=\frac{2125}{1000}\)

\(\frac{16}{25}=\frac{16.4}{25.4}=\frac{64}{100}\)

\(\frac{132}{125}=\frac{132.8}{125.8}=\frac{1056}{1000}\)

Tick đúng cho mình nhé

A

\(0,7=\frac{7}{10}\)

\(0,94=\frac{94}{100}\)

\(2,7=\frac{27}{100}\)

\(4,567=\frac{4567}{1000}\)

b)  \(\frac{1}{4}=\frac{25}{100}\)

\(\frac{7}{5}=\frac{14}{10}\)

\(\frac{16}{25}=\frac{64}{100}\)

\(\frac{3}{2}=\frac{15}{10}\)

\(0,7=\frac{7}{10}\)

\(0,94=\frac{94}{100}\)

\(2,7=\frac{27}{10}\)

\(4,567=\frac{4567}{1000}\)

b) \(\frac{1}{4}=\frac{25}{100}\)

\(\frac{7}{5}=\frac{14}{10}\)

\(\frac{16}{25}=\frac{64}{100}\)

\(\frac{3}{2}=\frac{15}{10}\)

~ Chúc bạn học giỏi ! ~

giúp mik vớiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii

a: \(0.5=\dfrac{5}{10}\)

\(0.019=\dfrac{19}{1000}\)

\(0.003=\dfrac{3}{1000}\)

b: \(1.6=\dfrac{16}{10}\)

\(-\dfrac{7}{20}=-0.35\)

\(-\dfrac{12}{15}=-0.8\)

\(-\dfrac{16}{500}=-0.032\)

\(5\dfrac{4}{25}=5\cdot\dfrac{16}{100}=5.16\)

-0,35

-2,4

-0,032

\(\dfrac{-7}{20}=-0,35\) 

\(\dfrac{-12}{15}=-0,8\) 

\(\dfrac{-16}{500}=-0,032\) 

\(5\dfrac{4}{25}=\dfrac{129}{25}=5,16\)
