Question

Answer 1

\(\dfrac{15}{4}=\dfrac{15 . 25}{4 . 25}=\dfrac{375}{100}\)
\(\dfrac{27}{20}=\dfrac{27 . 5}{20 . 5}=\dfrac{135}{100}\)
\(\dfrac{35}{50}=\dfrac{35 : 5}{50 : 5}=\dfrac{7}{10}\)
\(\dfrac{36}{90}=\dfrac{36 : 18}{90 : 18}=\dfrac{2}{5}=\dfrac{2 . 2}{5 . 2}=\dfrac{4}{10}\)
\(\dfrac{7}{125}=\dfrac{7 . 8}{125 . 8}=\dfrac{56}{1000}\)
\(\dfrac{9}{20}=\dfrac{9 . 5}{20 . 5}=\dfrac{45}{100}\)

Answer 2

15/4 = 3,75

27/20 = 1,35

35/50 = 0,7

36/90 = 0,4

7/125 = 0,056 

9/20 = 0,45

Answer 3

15/4 = 3,75

27/20 = 1,35

35/50 = 0,7

36/90 = 0,4

7/125 = 0,056 

9/20 = 0,45
