Question

The product of two rational numbers is 1/2 if one of them -2/3.Find the other.​

Answer 1

Answer:

Step-by-step explanation:

lets say two numbers are A and B and their product (multiplication) is C

A x B = C

if we know what B and C are then to find A is a task for children

A = C/B

here C is 1/2 and B is -2/3

thus A is $\frac{1/2}{-2/3}$

this can be written as $\frac{\frac{1}{2} }{\frac{-2}{3} }$

answer is thus - 3/4

if you're still confused think of this

1/2 ÷ -2/3 is just the same as 1/2 x -3/2

Answer 2

Answer:

-4/3

Step-by-step explanation:

let other rational number be x

now ,

according to question-

X ×(1/2)= - 2/3

so, x= (-2/3) ×(2×1) = (-4/3)
