Answer 1

Answer:

Product of two numbers = -49/2

One of them = 21/4

The other = -49/2÷21/4  

= -49/2x4/21

196/42

.

= -3/8

Answer 2

Answer:

Let the required number be x

According to the given problem,

$\frac{21}{4} x = - \frac{49}{2} \\ x = - \frac{49}{2} \times \frac{4}{21} \\ x = - \frac{7}{1} \times \frac{2}{3} \\ \boxed{x = - \frac{14}{3} }$

• Therefore, the other number is -14/3.
• -14/3 is the right answer.
