Question

7. Take a 2-digit number and reverse it. Now, subtract the smaller number from the larger number, Divide this subtraction by 9. What do you get as the remainder. Try the same game with two more two digt numbers, Tally the remainder in each case.​

Answer 1

Answer:

0

Step-by-step explanation:

Suppose we take 25, after reversing, it will be 52.

So, subtracting 52-25= 27.

Dividing 27 with 9, we will get 3 and remainder will be 0

Similarly, we take 72, after reversing, it will be 27.

So, substracting 72-27=45.

Dividing 45 with 9, we will get 5

Similarly, 45 is divisible by 9, so remainder is 0
