Question

please give all of answer in 5 mintues

Answer 1

First main:-

1. ans: The reciprocal of 1 is 1 itself. The reciprocal or multiplicative inverse is the number we have to multiply to obtain an answer equivalent to the multiplicative identity 1. The reciprocal of 1 is 1.

Therefore, the answer is option (a)

2. ans: The answer is option (c)

3. ans: The answer is option (c)

4. ans: The answer is 11 so, therefore it is option (b)

5. ans: The answer is 25 so, therefore it is option (d)

6. ans: The answer is 0.07 so, therefore it is option (c)

7. ans: The answer is 0.0756 so, therefore it is option (d)

8. ans: The answer is 232110 so, therefore it is option (b)

9. ans: The answer is 3 so, therefore it is option (a)

10. ans: The answer is 8/12 so, therefore it is option (c)

Second main:-

1. ans: 1000

2. ans: In the real numbers, zero does not have a reciprocal because no real number multiplied by 0 produces 1 (the product of any number with zero is zero).

3. ans: When you divide by a common fraction, multiply by the reciprocal:

2 ÷ (2/3)  =  2 x (3/2)  =  (2/1) x (3/2)  =  6/2  =  3

4. ans: 100

5. ans: The answer is -12/20.

Third main:-

1. ans: True

2. ans: 0/1 = 0, whereas, 1/0 is not defined. For example, if zero is to be divided by any number, this means 0 items are to be shared or distributed among the given number of people. So, in this case, there are no items to be shared, hence, no one will get any item. Hence, 0 divided by any divisor gives 0 as the quotient.

Therefore, it is false.

3. ans: True

4. ans: 1 Decameter: 1 Decameter is equal to exactly 10 meters.

Therefore, it is true.

5. ans: 0.06 multiplied by 100 u will get 6 paisa so it is true.
