\(52\times\left(x\div78\right)=3380\)
\(\Leftrightarrow x\div78=65\)
\(\Leftrightarrow x=5070\)
\(52\times\left(x\div78\right)=3380\)
\(x\div78=3380\div52\)
\(x\div78=65\)
\(x=65\times78\)
\(x=5070\)
Vậy \(x=5070\)
52x(y :78)=3380
y:55-y+33=76
x:\(\frac{1}{7}\)=14 ; \(\frac{8}{x}\)=\(\frac{20}{15}\); 52x\(\frac{x}{78}\)=3380
52 . ( x : 78 ) = 3380
Tìm y : 52 x ( y : 78 ) = 3380
Tìm y :
52 x ( y : 78 ) = 3380
52 x ( y : 78 ) = 3380
tìm χ :
52 x ( χ : 78 ) = 3380
(x-3,64) x 2,5 = 15,85
52 x ( y : 78 ) = 3380
52 x (x : 78)=3380
