(a)Given,  $(-3) \times \_\_\_\_\ = 27$

The product is positive, therefore there should be even number of negative integers.

$(-3) \times \underline{(-9)}= 27$

(b) Given, $5 \times \_\_\_\_\_ \ = -35$
The product is negative, therefore there should be odd number of negative integers.

$5 \times \underline{(-7)} = -35$

(c) $\_\_\_\_ \ \times (- 8) = -56$

The product is negative, therefore there should be odd number of negative integers.

$\underline{7}\times (- 8) = -56$

(d) $\_\_\_\ \times (-12) = 132$

The product is positive, therefore there should be even number of negative integers.

$\underline{(-11)} \times (-12) = 132$
