Question

viết năm phân số bằng phân số \(\dfrac{5}{7}\)

Answer 1

\(\dfrac{10}{14};\dfrac{15}{21};\dfrac{20}{28};\dfrac{25}{35};\dfrac{30}{42}\)

Answer 2

5/7 = 10/14 = 15/21 = 20/28 = 25/35 = 30/42

Answer 3

Năm số = phân số `5/7` là :

`10/14;15/21;20/28;25/35;30/42`

Answer 4

5 phân số bằng phân số \(\dfrac{5}{7}\) là:

\(\dfrac{5}{7}=\dfrac{5\times2}{7\times2}=\dfrac{10}{14}\)

\(\dfrac{5}{7}=\dfrac{5\times3}{7\times3}=\dfrac{15}{21}\)

\(\dfrac{5}{7}=\dfrac{5\times4}{7\times4}=\dfrac{20}{28}\)

\(\dfrac{5}{7}=\dfrac{5\times5}{7\times5}=\dfrac{25}{35}\)

\(\dfrac{5}{7}=\dfrac{5\times6}{7\times6}=\dfrac{30}{42}\)

Answer 5

\(\dfrac{5}{7}=\dfrac{5.2}{7.2}=\dfrac{10}{14},\dfrac{5}{7}=\dfrac{5.3}{7.3}=\dfrac{15}{21}\)\(,\dfrac{5}{7}=\dfrac{5.4}{7.4}=\dfrac{20}{28},\dfrac{5}{7}=\dfrac{5.5}{7.5}\dfrac{25}{35}\) \(\dfrac{5}{7}=\dfrac{5.6}{7.6}=\dfrac{30}{42}\)

Vậy 5 phân số bằng \(\dfrac{5}{7}\) là:\(\dfrac{10}{14},\dfrac{15}{21},\dfrac{20}{28},\dfrac{25}{35},\dfrac{30}{42}\)

Answer 6

\(\dfrac{10}{14}\),\(\dfrac{15}{24}\),\(\dfrac{20}{28}\),\(\dfrac{25}{35}\).\(\dfrac{30}{42}\),\(\dfrac{35}{49}\),\(\dfrac{40}{56}\),\(\dfrac{45}{63}\)
