Rounding decimals in Year 7 math is really important! It makes math easier and helps you see your answers more clearly.

Why Should We Round?

• Simplicity: When you add $3.67 + 4.89$, if you round $3.67$ to $3.70$, you get $3.70 + 4.90 = 8.60$. That’s much simpler!

• Estimation: Rounding helps you check if your answer makes sense.

Key Operations:

1. Addition: For $2.78 + 1.52$, you can round it to $3 + 2 = 5$ for a quick guess.

2. Subtraction: For $5.43 - 2.19$, round it to $5 - 2 = 3$.

3. Multiplication: With $4.23 \times 2.1$, just round it to $4 \times 2 = 8$.

4. Division: For $9.56 ÷ 2.4$, round it to $10 ÷ 2 = 5$.

Knowing how to round makes working with decimals so much easier!
