Question

x-3/5=2/3 nhân 1/5

Ai trả lời đúng đc 1 tick

Answer 1

\(x-\dfrac{3}{5}=\dfrac{2}{3}\times\dfrac{1}{5}\\ \Rightarrow x-\dfrac{3}{5}=\dfrac{2}{15}\\ \Rightarrow x=\dfrac{2}{15}+\dfrac{3}{5}\\ \Rightarrow x=\dfrac{2}{15}+\dfrac{9}{15}\\ \Rightarrow x=\dfrac{11}{15}\)

Answer 2

=>x-3/5=2/15

hay x=11/15

Answer 3

x-3/5=2/3 x1/5

x-3/5=2/15

x=2/15+3/5

x=2/15+9/15

x=11/15

Answer 4

\(x-\dfrac{3}{5}=\dfrac{2}{3}\times\dfrac{1}{5}\)

\(x-\dfrac{3}{5}=\dfrac{2}{15}\)

\(x=\dfrac{2}{15}+\dfrac{3}{5}\)

\(x=\dfrac{11}{15}\)

Answer 5

\(x-\dfrac{3}{5}=\dfrac{2}{3}x\dfrac{1}{5}\)

\(x-\dfrac{3}{5}=\dfrac{2}{15}\)

\(x=\dfrac{2}{15}+\dfrac{3}{5}\)

\(x=\dfrac{2}{15}+\dfrac{9}{15}\)

\(x=\dfrac{15}{11}\)

Answer 6

x−35=23×15⇒x−35=215
x=215+35⇒x=215+915⇒x=1115
