Given:

$(-11)$ multiplied by ________ multiplied by $(-11)=1210$.

To do:

We have to find the value of the blank.

Solution:

Let the required number be $x$.

We know that,

$(-)\times(-)=(+)$

Therefore,

$(-11)$ multiplied by $x$ multiplied by $(-11)=1210$

$[(-)\times(-)](11\times11)\times x=1210$

$121x=1210$

$x=\frac{1210}{121}$

$x=10$
 The required number is $10$.
