Question

Solve the following:

(1) What number should be multiplied by (−6) to get (+30) as product?

(2) If then, find the missing term.

(3) What number is multiplied by (−15) to get the product as (+90)

(4) If then, find the missing integer.

(5) If then, find the missing integer.

Answer 1

(1) Let the number be .

Thus, (−5) should be multiplied by (−6) to get (+30) as product.

(2) Let the missing term be .

(3) Let the number be .

Thus, (−6) should be multiplied by (−15) to get (+90) as product.

(4) Let the missing integer be .

(5)

The missing integer is 3.
