Question

rút gọn phân số nhanh giúp mik với:

-8/12

15/-60

-16/-72

35/14.15

Answer 1

\(\frac{-8}{12}=\frac{-2}{3}\)

\(\frac{15}{-60}=\frac{-1}{4}\)

\(\frac{-16}{-72}=\frac{2}{9}\)

\(\frac{35}{14.15}=\frac{1}{6}\)

Answer 2

\(\frac{-8}{12}=\frac{-2}{3}\\ \frac{15}{-60}=\frac{-1}{4}\\ \frac{-16}{-72}=\frac{2}{9}\\ \frac{35}{14.15}=\frac{1}{6}\)

Answer 3

\(-\frac{8}{12}=\frac{-8:4}{12:4}=-\frac{2}{3}\)

\(\frac{15}{-60}=-\frac{15}{60}=\frac{-15:15}{60:15}=-\frac{1}{4}\)

\(\frac{-16}{-72}=\frac{16}{72}=\frac{16:8}{72:8}=\frac{2}{9}\)

\(\frac{35}{14.15}=\frac{35}{210}=\frac{35:35}{210:35}=\frac{1}{6}\)
