Question: User: 0.7 X 0.06
1. **State the problem:** We need to multiply $0.7$ by $0.06$. 2. **Recall the multiplication rule for decimals:** When multiplying decimals, multiply as if they were whole numbers, then count the total number of decimal places in both factors to place the decimal point in the product. 3. **Multiply the numbers ignoring decimals:** $$7 \times 6 = 42$$ 4. **Count decimal places:** - $0.7$ has 1 decimal place. - $0.06$ has 2 decimal places. - Total decimal places = $1 + 2 = 3$. 5. **Place the decimal point:** Starting from the right of $42$, move the decimal point 3 places to the left: $$42 \rightarrow 0.042$$ 6. **Final answer:** $$0.7 \times 0.06 = 0.042$$
