Question

Tìm x :

( x * 216 ) : 8 = 1215

Answer 1

\(\left(Xx216\right):8=1215\)

\(X=\left(1215x8\right):216\)

\(X=9720:216\)

 \(X=45\)

Answer 2

(x*216):8=1215

x*216    =1215*8=9720

x          =9720:216

x          =45

Answer 3

\(\left(x\times216\right):8=1215\)

\(x\times216=1215\times8\)

\(x\times216=9720\)

\(x=9720:216\)

\(x=45\)

Answer 4

( x * 216) : 8 = 1215

x * 216 = 1215 x 8

x * 216 = 9720

x = 9720 : 216

x = 45

Vậy x = 45
 

Answer 5

{ X x 216 } : 8 = 1215

X = 1215 x 8 : 216

X = 9720 : 216

X = 45

{ 45 x 216 } : 8 = 1215

Answer 6

Số cần tìm là: 45

mik chỉ biết như vậy thôi !

Answer 7

( x * 216) : 8 = 1215

x * 216 = 1215 x 8

x = 9720 : 216

x = 45

Vậy x = 45

Answer 8

( x * 216) : 8 = 1215

x * 216 = 1215 x 8
