20,22 x 45 + 20,22 x 46 + 10,11 x 16 + 20,22

Answer 1

20,22 x 45 + 20,22 x 46 + 10,11 x 16 + 20,22

= 20,22 x ( 45 + 46 + 1 + 8) 

= 20,22 x 100 

= 2022

Answer 2

`=20,22xx(45+46+8+1)`

`=20,22xx100=2022`

Answer 3

20,22 x 45 + 20,22 x 46 + 10,11 x 16 + 20,22

`=20,22xx45+20,22xx46+10,11xx2xx8+20,22xx1`

`=20,22xx45+20,22xx46+20,22xx8+20,22xx1`

`=20,22xx(45+46+8+1)`

`=20,22xx100`

`=2022`

Answer 4

 

= 20,22 x ( 45 + 46 + 1 + 8)
