\(\frac{5}{6}=\frac{5x3}{6x3}=\frac{15}{18}\)

\(\frac{4}{9}=\frac{4x2}{9x2}=\frac{8}{18}\)

Vậy \(\frac{5}{6}=\frac{15}{18}\); \(\frac{4}{9}=\frac{8}{18}\)

•\(\frac{5}{6}=\frac{15}{18}\)

• \(\frac{4}{9}=\frac{8}{18}\)

cảm ơn các bạn nhé

a: 5/3=10/6=25/15=35/21

b: 5/7=35/49

6/15=12/30

4/5=16/20

c: 6=216/36=324/54=108/18

a)\(\dfrac{5}{3}=\dfrac{10}{6}=\dfrac{25}{15}=\dfrac{35}{21}\)

b)\(\dfrac{5}{7}=\dfrac{35}{49};\dfrac{6}{15}=\dfrac{12}{30};\dfrac{4}{5}=\dfrac{16}{20}\)

c) \(6=\dfrac{216}{36}=\dfrac{324}{54}=\dfrac{108}{18}\)

\(\frac{5}{6}=\frac{5x4}{6x4}=\frac{20}{24}\)

\(\frac{9}{8}=\frac{9x3}{8x3}=\frac{27}{24}\)

\(\frac{5}{6}\)và\(\frac{9}{8}\)

\(\frac{5}{6}=\frac{5\times4}{6\times4}=\frac{20}{24}\)

\(\frac{9}{8}=\frac{9\times3}{8\times3}=\frac{27}{24}\)

5/6=20/24

9/8=27/24 nha

Đúng

Skibo

5/6 = 10/12 

3/4 = 9/12

5/6

4/9

Msc:18

5/6=15/18

4/9=8/18

\(\dfrac{5}{6}=\dfrac{5\times3}{6\times3}=\dfrac{15}{18}\)

\(\dfrac{4}{9}=\dfrac{4\times2}{9\times2}=\dfrac{8}{18}\)

\(\dfrac{5}{6}=\dfrac{20}{24}\)

\(\dfrac{9}{8}=\dfrac{27}{24}\)

5/6 = 5 x 4/6 x 4 = 20/24

9/8 = 9 x 3/8 x 3 = 27/24

Tick xanh mình nhe!

5/4 và 6/7 nhé

\(\frac{5}{4}=\frac{70}{56}\)

\(\frac{6}{7}=\frac{48}{56}\)

Ta co : 5/6=20/24

             9/8=27/24

5/6 = 20/24 , 9/8 =27/24

5/6=20/24

9/8=27/24
