Decreases means division and increases means multiplication.Over here it says decreases and therefore it is division.For example let us take 100.(B) 100/ 1/10 = 100 * 10 = 1000(C)100/10 = 10Therefore,C is correct as 1 moves from left to right.

## Ans 11:

Class : Class 6

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

## Ans 12:

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 15:

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 20:

Class : Class 7

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 27:

Class : Class 8

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 29:

Class : Class 8

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

## Ans 36:

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 42:

Class : Class 6

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

## Ans 43:

Class : Class 6

answer should be C because it already says the word divide and if we write ans as B then it will become ( eg. 100/1/10 = 1000) hence it should be ( eg. 100/10 = 10) . PLS CORRECT IT SOF !!!!!

## Ans 45:

Class : Class 7

The answer is B cause they are saying step by step from LEFT to RIGHT that means it is increasing but as they have said decreasing the answer is B . eg- 10 increases by 10 when it goes from tens to hundred. So it decreases by this formula - 10 divided by 1/10 ( dividing a whole number by a fraction = whole number X the reciprocal of the fraction) = 10x10 = 100

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.
