Question

Bài 2 làm kiểu gì vậy mn

Answer 1

`160/320=(160:10)/(320:10)=16/32=(16:2)/(32:2)=8/16=(8:2)/(16:2)=4/8=1/2`

Answer 2

Bài 2:
\(\dfrac{160}{320}=\dfrac{16}{x}=\dfrac{y}{16}=\dfrac{4}{z}=\dfrac{1}{2}\)
\(x=\dfrac{16\times320}{160}=32\)
\(y=\dfrac{16\times16}{32}=8\)
\(z=\dfrac{4\times2}{1}=8\)
