How about: $2.4 \dot{9} \mathmr{and} 0.25 \times {10}^{1}$

#### Explanation:

(i) $2.4 \dot{9}$ (read "2.4 9 recurring") is equivalent to 2.50 since rounding the infinite decimal at any finite point will result in $2.50$

(ii) $2.50$ would not usually be written in scientific notation (as it is $2.5 \times {10}^{0}$). However it could be written as $0.25 \times {10}^{1}$
