Question

Find the missing digit so that the given number is divisible by 11; a) 2*583 b) 37*45

Answer 1

Answer:

According to the question,

The missing digit in the given numbers are

• a) missing digit = 2

actual number = 22583

• b) missing digit = 3

actual number = 37345

As in the question the answers 22583,37345 are divisible by 11.

Answer 2

Answer:

a)

we have to divide  the numbers into two that is odd and even we have to start  from the ones place then skip one number each so the no: 2*583

will be divided into two that is 2,5, and 3 will be even place and 8 and * will be in the odd place

Step-by-step explanation:

so we have to add the odd and even numbers so that will be

2+5+3=10

8+*=for this we have to  think how many times will make 10 so we can minus it from there

10-2=8

so 2+5+3= 10

8+2=10

then according to divisibility rule of 11, we have to add each number then we have to subtract the answer of addends so we will get 10-10 = 0

so the missing number is 2

and the actual no =22583

b) 37*45

even = 3,* and 5

odd = 7 and 4

so we will add the odd numbers so it will be

7+4 = 11

then we will add the numbers of the even place so that is

3+*+5 so we have to think what makes 11

so will be 3+6+5=11

then according to divisibility rule of 11, we have to add each number then we have to subtract the answer of addends so we will get 11 -11 = 0

so the missing number is 6

and the actual number is 37645
