Question

The product of two rational numbers is-7/8. If on is 5/14 find other.​

Answer 1

Answer:

$- 2 \frac{9}{20}$

Step-by-step explanation:

To find:

The other rational number

Given:

Product of two rational numbers = -7/8

One of them = 5/14

Assuming:

Let the other rational number be x

Solution:

ATQ.

$\frac{5}{14} \times x = \frac{ - 7}{8} \\ = > x = \frac{ - 7}{8} \div \frac{5}{14} \\ = > x = \frac{ - 7}{8} \times \frac{14}{5} \\ = > x = \frac{ - 98}{40} \\ = > x = \frac{ - 49}{20} = - 2 \frac{9}{20}$

Hence:

The other rational number =x= -2 whole 7/10

Verification:

LHS.

$\frac{5}{14} \times \frac{ - 49}{20} = \frac{ - 49}{14 \times 4} = \frac{ - 49}{56} = \frac{ - 7}{8}$

RHS= -7/8

Therefore LHS=RHS

Hence ,proved
