Question

What is the number? :) (Well the rest of it ;-;)

Answer 1

See where the arrow is pointing at in each of the scales.

---In the first scale, the arrow is clearly on the 300, so you have 300 grams.

---Now look at the second scale. The arrow is clearly on the 40, so add 300g + 40g = 340 grams.

---The last scale's arrow is between the 2 and 3. There are 10 ticks between 2 and 3, so that means each tick represents 0.1.

The arrow is on the first tick, so it represents 0.1 grams. Add 2 and 0.1 = 2.1 grams.

Now add 340g + 2.1g = 342.1 grams.

Answer:

The triple beam scale reads as 342.1 grams.
