$2.5 \times 10^{- 2}$ $2.5times10^-2$

To write a number in scientific notation, we can write as follows:

$a \times 10^{n}$ $atimes10^n$ , where $0 < a < 10$ $0< a<10$ and n is an integer.

In this question, the most probable value of $a$ $a$ would be $2.5$ $2.5$ .

$2.5 = 0.025 \times 100$ $2.5=0.025times100$

Therefore,
$0.025$ $0.025$

$= 0.025 \times 100 \div 100$ $=0.025times100divide100$

$= 2.5 \div 100$ $=2.5divide100$

$= 2.5 \times 10^{- 2}$ $=2.5times10^-2$

Note: $\frac{1}{10^{n}} = 10^{- n}$ $1/10^n=10^-n$
