Question

x - 3/5 = 1/3 : 2/15 (phân số nhé mn)

Answer 1

\(x-\dfrac{3}{5}=\dfrac{1}{3}:\dfrac{2}{15}\)

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

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

\(x=\dfrac{31}{10}\)

Answer 2

`x - 3/5 = 1/3 : 2/15 `

 

`x-3/5=5/2`

 

`x=5/2+3/5`

 

`x=31/10`.

Answer 3

\(x-\dfrac{3}{5}=\dfrac{1}{3}:\dfrac{2}{15}\)
\(x-\dfrac{3}{5}=\dfrac{1}{3}\times\dfrac{2}{15}\)
\(x-\dfrac{3}{5}=\dfrac{5}{2}\)
\(x=\dfrac{5}{2}+\dfrac{3}{5}=\dfrac{25+6}{10}\)
\(x=\dfrac{31}{10}\)

Answer 4

`x - 3/5 = 1/3 : 2/15`

`x - 3/5 = 1/3* 15/2 `

`x-3/5 = 15/6 = 5/2`

`x  = 5/2 +3/5 = 25/10+ 6/10`

`x = 31/10`

Vậy `x = 31/10`
