Ok To find the mass of two identical things of sardines, we can use the concept of proportionality.

If the mass of 20 identical things of sardines is 8.5 kg, we can set up a proportion:

20 things / 8.5 kg = 2 things / x kg

Cross-multiplying, we get:

20 things * x kg = 2 things * 8.5 kg

Simplifying, we have:

20x = 17

Dividing both sides by 20, we find:

x = 17/20

Therefore, the mass of two identical things of sardines is 17/20 kg, which is approximately 0.85 kg.
