the answer is C.. B is the wrong answer . if we have to move the digits from left to right we should multiply and not divide.. please clarify SOF..

## Ans 9:

Class : Class 6

the correct answer is [B] because
if we take a no. as 10.ok.then i am doing like example see-
10X1/10 so it is =1 so it decreased

## Ans 10:

Class : Class 4

I think answer is B.....as we have to divide the digit by number 10 each time we move from left to right .....and so its value decreases eg 500 is divided by 10 (500*1/10 = 50) to make its place value from hundred to tens

## Ans 13:

The correct answer is (C) because the question asks you by how many times it is DECREASING from LEFT TO RIGHT . If it said increasing, then the answer would be (B)

## Ans 15:

Class : Class 7

c is right because we have to multiply cause we are given times.. 1000x___= 100... so we get 1000/10= 10 so c is right

answer is bwhen we move from left to rightexample-1000 to 100how do you get 100 by dividing it by 10 right?i.e 1000/10 = 100answer = 1/10

## Ans 24:

The answer is c. It decreases by 1 by 10 when it goes from right to left, not from left to right.
