Answer 2

Answer:

The other number is (-3/5)

Step-by-step explanation:

Let the other number be x

Then, according to the Question,

x • (5/3) = (-1)

Solving for x,

x = (-1) ÷ (5/3)

x = (-1) × (3/5)

x = (-3/5)

Hence,

The other number was (-3/5)

We can also check this,

(5/3) • (-3/5) = (-1)

Cancelling the common factors, we get,

(-1) = (-1)

LHS = RHS

Hence, it is correct
