9/5 =

2/25 =

23/8 =

76/4 =

42/25 =

Answer 1

9/5 =18/10=1,8
 2/25 =8/100=0,08
23/8 =2874/1000=2,874
76/4 =1900/100=19
42/25 =168/100=1,68

 

Answer 2

9/5 = 18/10 = 1,8

2/25 = 8/100 = 0,08

23/8 = 2875/1000 = 2,875

76/4 = 1900/100 = 19,00 = 19

42/25 = 168/100 = 1,68

Answer 3

9/5 =\(\dfrac{90}{50}=1,8\)

2/25 =\(\dfrac{20}{250}=0,08\)

23/8 =\(\dfrac{23}{8}=2,875\)

76/4 =\(\dfrac{76}{40}=\dfrac{19}{10}\)

42/25 =\(\dfrac{420}{250}=1,68\)

Answer 4

\(\dfrac{9}{5}=\dfrac{18}{10}=1,8\)

\(\dfrac{2}{25}=\dfrac{8}{100}=0,08\)

\(\dfrac{23}{8}=\dfrac{2875}{1000}=2,875\)

\(\dfrac{76}{4}=\dfrac{1900}{100}=19\)

\(\dfrac{42}{25}=\dfrac{168}{100}=1,68\)

Answer 5

9/5 =18/10=1,8
 2/25 =8/100=0,08
23/8 =2874/1000=2,874
76/4 =1900/100=19
42/25 =168/100=1,68
