Question

Tìm Y , 68 x ( Y : 35 ) = 1156, 111315 : ( Y x 123 ) = 181

 

 

 

 

 

Answer 1

a)68x(y:35)=1156

⇔ y:35=1156:68

⇔ y:35= 17

⇔ y = 17 x 35

⇔ y = 595

b) 111315:(Y x 123)=181(k chia hết)

⇔ y x 123=  

Answer 2

68 x ( x : 35 ) = 1156

X : 35 = 1156 : 68

X : 35 = 17

X = 17 x 35

X = 595

$111315:(x\times 123)=181$

$x\times 123=111315:181$

$x\times 123=615$

$x=615:123$

$x=5$

Vậy $x=5$

Answer 3

$68\times (x:35)=1156$

$x:35=1156:68$

$x:35=17$

$x=17\times 35$

$x=595$

b)

$111315:(x\times 123)=181$

$x\times 123=111315:181$

$x\times 123=615$

$x=615:123$

$x=5$

Vậy $x=5$
