Answer:
-2/7
Step-by-step explanation:
Rational number to be multiplied = X
Other rational number to be multiplied = -3/7
Result of the multiplication of these rational numbers = 6/49
According to the question
X × (-3/7) = (6/49)
- 3/7X = 6/49
X = 6/49 × (-7/3)
X = - 2/7
Rational number to be multiplied = - 2/7
Check
(-2/7) × (-3/7) = 6/49
6/49=6/49
Hence checked
-2/7 should be multiplied with - 3/7 to get 6/49
