Question

the product of two numbers is 4/7 . if one of the number is 3/-4 , then find the other number

Answer 1

$\frac{3}{ - 4} \times x = \frac{4}{7} \\ \\ x = \frac{4}{7} \div \frac{3}{ - 4} \\ \\ x = \frac{4}{7} \times \frac{ - 4}{3} \\ \\ x = \frac{ - 16}{21}$

hope this helps....

Answer 2

Step-by-step explanation:

Let the unknown number be x

Given that,

Product of two numbers =

$\frac{4}{7}$

One number =

$\frac{3}{ - 4}$

Therefore,

$x \times \frac{3}{ - 4} = \frac{4}{7} \\ x = \frac{4}{7} \times \frac{ - 4}{3} \\ x = \frac{4 \times ( - 4)}{7 \times 3} \\ x = \frac{( - 16)}{21}$

Cross Check:

$\frac{ - 16}{21} \times \frac{3}{ - 4} \\ = \frac{4}{7}$

Hence, the answer is:

$\frac{ - 16}{21}$

Hope this answer will help you with the question
