Question

tìm x 

x : 10 : 12 = 41            

x * 15 * 6 =270

 

Answer 1

x=41x12x10=4920

x=270:6:15=3

Answer 2

a) =>x=41.10.12=4920

b) =>x.90=270 

    =>x=\(\dfrac{270}{90}=3\)

Answer 3

x:10:12=41

<=>x:10=41x12

<=>x:10=492

<=>x=492x10

<=>x=4920

x*15*6=270

<=>x*15=270:6

<=>x*15=45

<=>x=45:15

<=>x=3

Answer 4

\(a,x:10:12=41\\ x:10=41\times12\\ x:10=492\\ x=492\times10\\ x=4920\\ ----\\ b,x\times15\times6=270\\ x\times15=270:6\\ x\times15=45\\ x=45:15\\ x=3\)

Answer 5

X=41 x 12 x 10 = 4920

X= 270 : 6 : 15 = 3

Answer 6

*) x : 10 : 12 = 41

x : 10 = 41 × 12

x : 10 = 492

x = 492 × 10

x = 4920

*) x × 15 × 6 = 270

x × 15 = 270 : 6

x × 15 = 45

x = 45 : 15

x = 3
