Question

Choose the correct answer and fill the blank for$-15\times \_\_\_\_\_=15$

• A. $-1$
• B. $+1$

Answer 1

The correct option is A

$-1$

Explantion for correct option:

For solving $-15\times \_\_\_\_\_=15$

Whenever the number is multiplied by $1$ then the answer remains the same

On multiplying $-ve\times (-ve)=+ve$

It means $-15$ must be multiplied by $-1$ so as to get $15$ an answer like $-15\times (-1)=15$

For getting an answer as $15$ we must have to multiply $-15$ by $-1$

So the answer is $-1$

Hence, option(A) is correct.
