Question

the price of two rational numbers is 5/18 if one of them is 3/20 find the other number​

Answer 1

Answer:

ATQ, the product of two rational number is 5/18 and one of them is minus -3/20

let the other one be x

➡ x(-3/20) = 5/18

➡ -3x/20 = 5/18

➡ -3x = 5/18 × 20

➡ -3x = 5/9 × 10

➡ -3x = 50/9

➡ x = 50/9 × 1/-3

➡ x = 50/-27 = -50/27

hence, the other rational number is -50/27

verification :-

= -50/27 × -3/20

= 5/9 × 1/2

= 5/18
