Answer:
125.4
Step-by-step explanation:
Given
[tex]Number = 125.3546[/tex]
Required
Round to 1 decimal place
Up till the first decimal place, the number is:
[tex]Number = 125.3[/tex]
The digit after .3 is 5
The conditions for approximation are:
- If n > 4, approximate to 1
In this case: 5 > 4, so we approximate to 1
Add this "1" to the last digit of 125.3. This becomes 125.4
Hence: when the number is approximated to 1 decimal place, the digit is 125.4
