Question

 y : \(\frac{1}{7}\)= 15,4 + 41,3.

Answer 1

x:1/7=15,4+41,3

x:1/7=56,7

x=56,7x1/7

x=8,1          

Answer 2

\(y:\frac{1}{7}=15,4+41,3\)

\(\Rightarrow y:\frac{1}{7}=56,7\)

\(\Rightarrow y=56,7.\frac{1}{7}=8,1\)

vậy y = 8,1

Answer 3

y : 1/7 =  56,7

y = 56,7 x 1/7

y = 8,1

Answer 4

\(y:\frac{1}{7}=15,4+41,3\)

\(y:\frac{1}{7}=56,7\)

\(y\)   \(=56,7.\frac{1}{7}\)

\(y\)    \(=\frac{81}{10}\)

Vậy\(y=\frac{81}{10}\)

Answer 5

y : \(\frac{1}{7}\)= 15,4 + 41,3

y : \(\frac{1}{7}\)= 56,7

      y       = 56,7 . \(\frac{1}{7}\)

       y      = 8,1

Vậy y = 8,1

Answer 6

\(y\div\frac{1}{7}=15,4+43,3\)

\(y\div\frac{1}{7}=58,7\)

\(y=58,7\times\frac{1}{7}\)

\(y=\frac{81}{10}\)

\(y=8,1\)
