Question

the product of two rational number is minus 3 upon 7 if one of the number is 5.21 find the other ​

Answer 1

Step-by-step explanation:

let the two numbers be x and y

Given x = 5.21

Then x . y = -3/7

=> 5.21 × y = -3/7

=> y = -3/7×5.21

=> y = -0.082

Answer 2

-3/7 (x) =5.21

-3(x). =5.21(7)

-3(x). =36.47

(x). =36.47/-3

x. =12.15 (approx)
