Questions: Round 25.45999 to three significant figures. 25.4 26.0 25.5 25.0

Solution Steps

To round a number to three significant figures, we need to consider the first three digits of the number and round the last of these digits based on the digit that follows it.

We start with the number \( 25.45999 \).

We need to round this number to three significant figures. The first three significant figures of \( 25.45999 \) are \( 2 \), \( 5 \), and \( 4 \).

To round to three significant figures, we look at the fourth digit (which is \( 5 \) in this case). Since \( 5 \geq 5 \), we round the third digit up by 1.

Rounding \( 25.45999 \) to three significant figures results in \( 25.46 \).
