Question

Tìm x, biết:
2 phần 5 : x = 1 phần 26 : 0,125

Answer 1

\(\dfrac{2}{5}:x=\dfrac{1}{26}:\dfrac{1}{8}\\ \dfrac{2}{5}:x=\dfrac{4}{13}\\ x=\dfrac{2}{5}:\dfrac{4}{13}\\ x=\dfrac{13}{10}\)

Answer 2

2/5:x=1/26:125/1000

2/5:x=1/26:1/8

2/5:x=4/13

x=2/5:4/13

x=13/10

 

Answer 3

`2/5 : x = 1/26 xx 8`

`2/5 : x = 4/13`

`x = 2/5 xx 13/4`

`x=  13/10`

Answer 4

\(\dfrac{2}{5}:x=\dfrac{1}{26}:0,125\)

\(\dfrac{2}{5}:x=\dfrac{1}{26}:\dfrac{1}{8}\)

\(\dfrac{2}{5}:x=\dfrac{4}{13}\)

\(x=\dfrac{2}{5}:\dfrac{4}{13}=\dfrac{13}{10}\)
