Its given 1.431 i.e the point is at before three number. Hence we can write:
= 1431/1000.
Now its divide by 3.
= 1431/3-1000.
i.e 477/1000 = 0.477.
Because the numbers of zero three hence the point comes in before three number.
= 1431/1000.
Now its divide by 3.
= 1431/3-1000.
i.e 477/1000 = 0.477.
Because the numbers of zero three hence the point comes in before three number.
