Solved problems: Arranging items from lightest to heaviest.

📚 Quick Study Guide

• ⚖️ Weight is a measure of how heavy something is. We often use grams (g) and kilograms (kg) to measure weight. 1 kg = 1000 g.
• 📏 To arrange items from lightest to heaviest:
• 👁️‍🗨️ First, make sure all the weights are in the same units. If not, convert them.
• 🔢 Next, compare the numbers. The smaller the number, the lighter the item.
• 📝 Finally, list the items in order from the smallest weight to the largest weight.
• 💡 Tip: When comparing, think about everyday objects. For example, a feather is very light (grams), while a car is very heavy (kilograms or even tonnes!).
