          BẠN CHO MÌNH NHA

2/3 ; 3/4 ; 1/2 ; 4/9

ủng hộ mình lên 100 nha

\(\frac{4}{6}=\frac{4:2}{6:2}=\frac{2}{3};\frac{9}{12}=\frac{9:3}{12:3}=\frac{3}{4};\frac{10}{20}=\frac{10:10}{20:10}=\frac{1}{2};\frac{8}{18}=\frac{8:2}{18:2}=\frac{4}{9}\) 

bó tay

5 phần 20 với 25 phần 100 với 8 phần 32 đúng không ??

Đúng thì tk nha

5/20 = 25/ 100

a) \(\dfrac{8}{16}=\dfrac{8:8}{16:8}=\dfrac{1}{2}\)

b) \(\dfrac{10}{30}=\dfrac{10:10}{30:10}=\dfrac{1}{3}\)

c) \(\dfrac{24}{18}=\dfrac{24:6}{18:6}=\dfrac{4}{3}\)

d) \(\dfrac{20}{28}=\dfrac{20:4}{28:4}=\dfrac{5}{7}\)

\(a,\\ =\dfrac{5}{4}-\dfrac{3}{4}=\dfrac{2}{4}=\dfrac{1}{2}\\ b,\\ =\dfrac{2}{3}-\dfrac{2}{5}=\dfrac{10-6}{15}=\dfrac{4}{15}\\ c,\\ =\dfrac{5}{6}-\dfrac{1}{4}=\dfrac{20-6}{24}=\dfrac{14}{24}=\dfrac{7}{12}\\ d,\\ =\dfrac{4}{3}-\dfrac{1}{4}=\dfrac{12-3}{12}=\dfrac{9}{12}=\dfrac{3}{4}\)

 cảm ơn chị ạ
