Interactive weight measurement activity with a digital scale and input field.

Looking at the image, this is a digital scale calibration or reading exercise from an educational program (likely “Ohaus” brand, as seen in the top right).

## 🎯 Task:
> *“In this exercise the computer will select a random weight and set the three scales to that value. You then read the scales and enter your value in the text box to the right. Press the ‘Check Weight’ button and the program will compare your value to the true value.”*

You are shown three different scales, each representing part of the total weight:

1. Top Scale (Grams - 0 to 100g) → reads 48.0 g
*(The pointer is between 40 and 50, exactly on the 8th small tick after 40 → 40 + 8 = 48)*

2. Middle Scale (Hundreds of grams - 0 to 400g) → reads 300 g
*(Pointer is exactly on the 300 mark)*

3. Bottom Scale (500g increment) → reads 500 g
*(Pointer is exactly on the 500g mark — this is likely the largest increment scale)*

---

## ✔ Step-by-Step Calculation:

Add up all three readings:

> 500 g (from bottom scale)
> + 300 g (from middle scale)
> + 48.0 g (from top scale)
> = 848.0 g

## 💡 Important Note:
The instructions say:
> *“One place past the decimal is read with certainty, the second place past is estimated and considered inaccurate.”*

This means we should report the answer to one decimal place — which we already have: 848.0 g

---

## 📥 Final Answer to Enter:
> 848.0

*(Enter this into the text box labeled “Enter your weight here” and press “Check Weight”)*

---

✔ Why this works:
This is how triple-beam or multi-scale balances work — you add the values from each scale (hundreds, tens, units/decimals) to get the total mass.
