\(\dfrac{50}{60}=\dfrac{5}{6}\)
\(\dfrac{33}{11}=3\)
\(\dfrac{16}{60}=\dfrac{4}{15}\)
\(\dfrac{42}{22}=\dfrac{21}{11}\)

chia là gì z

50/60=5/6

33/11=3

16/60=4/15

42/22=21/11

D. 2/5

ta có 252=2².3².7

BCNN?(-142,252)=2².3².7=252

=\(\dfrac{-142}{252}\)

tick cho mk 

\(=\frac{5}{3}\)

5 nhé

=5/3 nha

\(\dfrac{5}{6}\)

9/12

 \(\dfrac{45}{60}\)=\(\dfrac{45:5}{60:5}\)=\(\dfrac{9}{12}\)

107/30

107/30

\(\dfrac{107}{30}\)

\(a,\dfrac{60}{108}=\dfrac{60:12}{108:12}=\dfrac{5}{9}\\ b,\dfrac{36}{126}=\dfrac{36:18}{126:18}=\dfrac{2}{7}\)

Trả lời đi mình sẽ tick ạ

a) = \(\dfrac{5}{9}\)

b) = \(\dfrac{2}{7}\)

\(\frac{60}{12}=\frac{60:12}{12:12}=\frac{5}{1}=5\)

Cho mình 1 đ-ú-n-g nha bạn!!!!!!!!!!

\(\frac{60}{12}=\frac{60:6}{12:6}=\frac{10}{2}=\frac{10:2}{2:2}=\frac{5}{1}\)
