Well you can use a positive and a negative number. The number doesn't matter. As long as their is a positive and a negative, multiplying them will always end up with a negative product. Examples are: -3 · 7 = -21. Or 10 · -2 = -20. Hope this helps you :)

If 2 liters of sea water contain 70 grams of salt, how much salt is in 32 liters of sea water?
OLga [1]

Answer:

1120 grams

Step-by-step explanation:

The amount of sea water is directly proportional to the amount of salt in the water.

Let the amount of sea water be W and the amount of salt be S.

This means that:

W α S

=> W = kS

where k = constant of proportionality

2 liters of sea water contain 70 grams of salt Therefore:

2 = k * 70

k = 2 / 70 = 1/35

Therefore, for 32 liters of sea water:

32 = 1/35 * S

S = 35 * 32

S = 1120 grams

There are 1120 grams of salt in 32 liters of water.
