1. x = 405

2. y = 1/3

3. x = 37/245

4. 0

1= 405

2 = 67/201

3 = 37/245

4 = 0

1/3 nhe

   162/67 x Y = 270/335

                 Y = 270/335 : 162/67

                 Y =  1/3 nhé

y=3 nha bạn. đi!

y = 3 nha bạn

y=3 nha bạn

 162/67 . y= 270/335

      162/67 . y = 54/67

          y = 54/67 : 162/67 = 54/67 . 67/162

          y = 54/162 = 1/3

\(y=\frac{270}{335}:\frac{162}{67}\)

\(y=\frac{1}{3}\)

162/67*y=270/335

y=270/335:162/67

y=135/405

y=1/3

162 / 57 x y = 270 / 335

               y  = 270 / 335 : 162 / 57

               y  = 19 / 67

Vậy , y = 19 / 67

\(\frac{162}{57}\)x y = \(\frac{270}{335}\)

y = \(\frac{270}{335}\): \(\frac{162}{57}\)

y = \(\frac{19}{67}\)

Chúc bạn học tốt!

703/3283

y= 270/335 - 145/245

y= 703/3283

y+ 145/245=270/335

=>y+29/49=54/67

=> y=54/67-29/49

=> y=703/3283

\(\frac{162}{67}\)x     \(y\) \(=\) \(\frac{270}{335}\) 

\(y=\)\(\frac{270}{335}:\frac{162}{67}\)

\(y=\)\(\frac{1}{3}\) \(k\) \(nha\) \(!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!\)

y = 1/3 nha bn
