Question

If 6 bottles of perfect water weigh a total of 4 kilograms (kg), what is the weight of 9 bottles?

Answer 1

6/4 = 9/x....6 bottles to 4 kg = 9 bottles to x kg
cross multiply
(6)(x) = (9)(4)
6x = 36
x = 36/6
x = 6 kg <===

Answer 2

Hi. To complete this problem you simply need to multiply:

9/6 x 4 = 6kg

I hope this helps. If you have any questions, please don't hesitate to ask.

Take care,
