A.1/3 this is your answer hopefully it is right!!
Answer:
The number '1' is called the 'multiplicative identity' of a number '-12/13' because it does not change the number '-12/13' after getting multiplied by it.
Therefore, option (B) is true.
Step-by-step explanation:
We know that when a number let say 'n' get multiplied by '1', it remains unchanged.
i.e.
The number '1' is called the 'multiplicative identity' of a number 'n' because it does not change the number 'n' after getting multiplied by it.
Given the number
-12/13
Multiply the number '-12/13' by '1'.
i.e.
-12/13 × 1 = -12/13
1 × -12/13 = -12/13
Thus, the number '1' is called the 'multiplicative identity' of a number '-12/13' because it does not change the number '-12/13' after getting multiplied by it.
Therefore, option (B) is true.
To solve this problem we can use equation.
If we assume that x is number of crocodiles, we can say that number of alligators is 4*x because its 4 times more.
We know that together is 40, so we have
x+4*x=40
Now we are reducing.
5x=40 /:5 dividing both sides by 5
x=9 - number of alligators
