Multiplying decimals by 10 is a straightforward process. When you multiply a decimal by 10, you simply shift the decimal point one place to the right. This is because multiplying by 10 increases the value by a factor of 10.
Here’s how to do it step by step:
- Identify the decimal number you want to multiply by 10.
- Move the decimal point in that number one place to the right.
- If there are no digits to the right of the decimal, you can add a zero.
Examples:
-
Example 1:
- Original number: 2.5
- Multiply by 10: 2.5 × 10 = 25.0 (The decimal point moves from between 2 and 5 to after the 5)
-
Example 2:
- Original number: 0.6
- Multiply by 10: 0.6 × 10 = 6.0 (The decimal point moves from between 0 and 6 to after the 6)
-
Example 3:
- Original number: 3.14
- Multiply by 10: 3.14 × 10 = 31.4 (The decimal point moves from between 3 and 1 to after the 1)
-
Example 4:
- Original number: 0.05
- Multiply by 10: 0.05 × 10 = 0.5 (The decimal moves from between 0.0 and 5 to after the 5)
Remember, if the original number is a whole number (like 7), multiplying by 10 simply adds a zero to the end (7 × 10 = 70).
