=> x+ 3/10=26273/10
=> x=26273/10-3/10
=>x=2627
mong là đúng!!
\(x+30\%x=2627.3\)
\(\Leftrightarrow130\%x=2627.3\)
\(\Leftrightarrow\dfrac{130}{100}\cdot x=2627.3\)
\(\Leftrightarrow x=2021\)
x + 30% x = 2627,3
1x + \(\dfrac{3}{10}\) x = 2627,3
x. ( 1 + \(\dfrac{3}{10}\) ) = 2627,3
x. ( \(\dfrac{10}{10}\) + \(\dfrac{3}{10}\)) = 2627,3
x. \(\dfrac{13}{10}\) = 2627,3
x = \(\dfrac{26273}{10}\) : \(\dfrac{13}{10}\)
x = \(\dfrac{26273}{10}\) . \(\dfrac{10}{13}\)
x = \(\dfrac{221}{1}\) . \(\dfrac{1}{1}\)
x = 221
Chúc bạn học tốt nhé !
x+30%x=2627,3
x.(1+30%)=2627,3
x.\(\dfrac{13}{10}\) =2627,3
x =2627,3: \(\dfrac{13}{10}\)
x =2021
x+30%x=2627,3
x+30%x=26273/10
x+3/10x=26273/10
1x+3/10x=26273/10
x.(1+3/10)=26273/10
x.13/10=26273/10
x. =26273/10:13/10
x. =2021
Chúc bạn thi tốt nha!
