bạn ơi
bạn có thể viết rõ phân số ra dc ko
VD: 12 phần 15 thì viết là 12/15 hoặc \(\dfrac{12}{15}\) nhé
a,\(\dfrac{44}{77}=\dfrac{44:11}{77:11}=\dfrac{4}{7}\)
b\(\dfrac{72}{90}=\dfrac{72:9}{90:9}=\dfrac{8}{9}\)
`27/81=(27:27)/(81:27)=1/3`
`57/76=(57:19)/(76:19)=3/4`
`35/84=(35:7)/(84:7)=5/12`
`MSC:12`
`1/3=(1xx4)/(3xx4)=4/12`
`3/4=(3xx3)/(4xx3)=9/12`
`5/12` giữ nguyên
\(\dfrac{27}{81}=\dfrac{1}{3}\); \(\dfrac{57}{76}=\dfrac{3}{4}\); \(\dfrac{35}{84}=\dfrac{5}{12}\)
\(\dfrac{1}{3}=\dfrac{4}{12}\)
\(\dfrac{3}{4}=\dfrac{9}{12}\)
Giữa nguyên 5/12
\(\frac{72}{84}=\frac{6}{7}\) nha

~~~~~~~~~~~~~~~~~~~~~~~~~~
\(\dfrac{360}{504}\) = \(\dfrac{360:72}{504:72}\) = \(\dfrac{5}{7}\);
\(\dfrac{72}{84}\) = \(\dfrac{72:12}{84:12}\) = \(\dfrac{6}{7}\)
