Can i please get help with this question?

Answer 1

1,5 . n = 13,65

We know:

`1,5=(15)/(10)`

and

`13,65=(1365)/(100)`

So,

`(15)/(10).n=(1365)/(100)`

Pass
`(15)/(10)` as division.

`n = ((1365)/(100))/((15)/(10))`

Btw, we also know:

`((a)/(b))/((c)/(d))=(a.d)/(b.c)`

So,

`n = ((1365)/(100))/((15)/(10))`

`n = (1365.10)/(100.15)`

`n = (13650)/(1500)`

`n = (91)/(10)`

`n = 9,1`
