Answer 2

Explanation:

LETS TAKE A EG.

1×1/5

NOW MAKE 1 BIGGER THAN 5

TO DO THIS ADD A ZERO AFTER 1 AND MULTIPLT IT WITH 10^-1

SO IT BECOMES

10 × 10^(-1) / 5

IF ITS DIVIDED BY LIKE 1/50 YOU WILL HAVE TO ADD TWO ZERO AND SO

IT WILL

100 × 10^(-2) /50

[IT MEANS THAT THE NO.OF ZERO YOU ADD THE NO. OF POWER TOU HAVE TO TAKE BUT IN NEGATIVE[10×10^-1][100×10^-2][1000×10^-3]LIKE THAT

NOW THAT THE NUMRITOR IS BIG IT IS EASY FOR YOU TO DEVIDE

10 × 10 ^-1 / 5 = 2 ×10^-1

(YOU CAN ALSO WRITE 10^-1 , 0.1 ALSO)

NOW

MULTIPLY

2 × 0.1 = 0.2
