x:1/7=15,4+41,3
x:1/7=56,7
x=56,7x1/7
x=8,1
\(y:\frac{1}{7}=15,4+41,3\)
\(\Rightarrow y:\frac{1}{7}=56,7\)
\(\Rightarrow y=56,7.\frac{1}{7}=8,1\)
vậy y = 8,1
\(y:\frac{1}{7}=15,4+41,3\)
\(y:\frac{1}{7}=56,7\)
\(y\) \(=56,7.\frac{1}{7}\)
\(y\) \(=\frac{81}{10}\)
Vậy\(y=\frac{81}{10}\)
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
\(y\div\frac{1}{7}=15,4+43,3\)
\(y\div\frac{1}{7}=58,7\)
\(y=58,7\times\frac{1}{7}\)
\(y=\frac{81}{10}\)
\(y=8,1\)
