\(4=\frac{5}{\frac{5}{4}}\)        ; \(4=\frac{8}{2}\)         ;\(4=\frac{12}{3}\)

\(\frac{20}{5};\frac{32}{8};\frac{48}{12}.\)

k mình nha! Mình trả lời đầu tiên đó!

1/2+1/5=7/10

hok TỐT

ta có 1/2 +1/5=7/10

nhó mick cho mình nha

\(\frac{8}{2};\frac{16}{4};\frac{24}{6}\)

Tất cả rút gọn bằng 4

\(\frac{8}{2}\),\(\frac{16}{4}\),\(\frac{24}{6}\)

Bài 7: Các phân số bằng nhau là:

\(\frac34=\frac{9}{12}=\frac{27}{36};\frac57=\frac{15}{21}=\frac{30}{42}\)

Bài 6:

\(3=\frac{3\times4}{1\times4}=\frac{12}{4};3=\frac{3\times5}{1\times5}=\frac{15}{5}\)

4phần2

4phần4

4phần6

\(\frac{4}{2}\);\(\frac{4}{4}\);\(\frac{4}{6}\)

+)\(\frac{4}{2}=2\)

+)\(\frac{4}{4}=1\)

+)\(\frac{6}{4}=\frac{3}{2}\)

\(\dfrac{12}{4};\dfrac{15}{5}\)

12/4; 15/5 nhé

\(\frac{5}{3};\frac{10}{6};\frac{25}{15};\frac{35}{21}\)

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