If the product of two rational numbers is (-9/16) and one of them is (-4/15) find the other number.​
ololo11 [35]

Given:

  • The product of two numbers is (-9/16).
  • One of the numbers is (-4/15)

To find: The other number.

Answer:

Let's assume the unknown number to be 'x'.

(-4/15) × x = (-9/16)

× = (-9/16) ÷ (-4/15)

When we divide a fraction by another fraction, the divisor will be taken in its reciprocal form.

x = (-9/16) × (-15/4)

x = 135/64

Therefore, the other number is 135/64.

Hope it helps. :)
