Round the number 125.3546 to 1 decimal place.

Answer 1

125.4

Explanation:

Given

`Number = 125.3546`

Required

Round to 1 decimal place

Up till the first decimal place, the number is:

`Number = 125.3`

The digit after .3 is 5

The conditions for approximation are:

• If n > 4, approximate to 1

• Else: approximate to 0

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
