ai đó giúp mình đi

vvvvvvvvvvvvvvvvvvvffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff

a, \(\frac{20}{48}\)=\(\frac{10}{24}\)=\(\frac{15}{36}\)=\(\frac{25}{60}\)=\(\frac{30}{72}\)=\(\frac{35}{84}=\frac{40}{96}\)

Còn phần b bye bye nhé

các bạn giải chi tiết có đc ko

mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm

a) \(\dfrac{-12}{16}=\dfrac{-15}{20}=\dfrac{-18}{24}=\dfrac{-21}{28}=\dfrac{-24}{32}=\dfrac{-27}{36}=\dfrac{-30}{40}=\dfrac{-33}{44}=\dfrac{-36}{48}=\dfrac{-39}{52}\)

\(=\dfrac{-42}{56}=\dfrac{-45}{60}=\dfrac{-48}{64}=\dfrac{-51}{68}=\dfrac{-54}{72}=\dfrac{-57}{76}=\dfrac{-60}{80}=\dfrac{-63}{84}=\dfrac{-66}{88}=\dfrac{-69}{92}\)

\(=\dfrac{-72}{96}=\dfrac{-75}{100}\)

Bài Làm

20/48 = 10/24 = 30/72 = 40/96 = 15/36 = 25/60 = 35/84 

Chỉ có vậy thui nha !

tkkk nha :)
