The correct answer is C as 100/10 is 10, 1000/100 is also 10.

Class : Class 6
ans should be C

## Ans 4:

Class : Class 8
it should be B as it is decreased by not increased if it was increased than it was 10

## Ans 5:

Class : Class 6
Ans should be (c)

Class : Class 7

## Ans 7:

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

Class : Class 6

## Ans 9:

Class : Class 6
Answer should be C

## 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 11:

Class : Class 7
decreasing by 1/10 is not possible . the answer should be (c)

Class : Class 4
Its C

Class : Class 6
c

Class : Class 6
Ans is (c).

## Ans 15:

Class : Class 6
how can it decrease by 1/10. it changes by 1/10 and decreases by 10 times answer should be C

Class : Class 7

## Ans 17:

Class : Class 7
answer should be Cas 100 /10 is 10

## Ans 18:

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

## Ans 19:

Class : Class 6
The and should be C

## Ans 20:

Class : Class 6
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 21:

Class : Class 7
As he is saying times, it should be 10 and not 1/10. So, answer should be C

## Ans 22:

Class : Class 7
correct ans. should be C

## Ans 23:

Class : Class 5
correct ans. should be C

Class : Class 6
ans should be c

## Ans 25:

Class : Class 7
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 26:

Class : Class 6
Ans c only makes sense

## Ans 27:

Class : Class 7
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 28:

Class : Class 8

## Ans 29:

## Ans 2:

Class : Class 7
hey , it is 90 tenths cause tenths means at the tenths place only . But if if there is another no. like 90 tenths we should multiply . But if you choose hundredth tenths it it will become in thousands value.
