e đang cần gấp ạ

Answer 1

\(\dfrac{75}{100}=\dfrac{3}{4};\dfrac{63}{126}=\dfrac{1}{2}\\ \dfrac{36}{27}=1\dfrac{1}{3};\dfrac{81}{54}=1\dfrac{1}{2};\dfrac{105}{405}=\dfrac{7}{27}\)

Answer 2

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

\(\dfrac{1}{2}\)

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

\(\dfrac{3}{2}\)

\(\dfrac{4}{15}\)

Answer 3

75/100= 75:25/100:25= 3/4

63/126= 63:63/126:63= 1/2

36/27= 36:6/27:9= 4/3

81/54= 81:27/54:27= 3/2

108/405= 108:27/404:27=4/15

Answer 4

\(\dfrac{75}{100}=\dfrac{3}{4};\dfrac{63}{126}=\dfrac{1}{2};\dfrac{36}{27}=\dfrac{4}{3};\dfrac{81}{51}=\dfrac{3}{2};\dfrac{108}{405}=\dfrac{4}{15}\)
