Answer 2

Step-by-step explanation:

$1.(2.30 \times 10 - 15 )= 23 \times \frac{10}{100} - 15 \\ \\ = \frac{23}{10} - 15 \\ \\ = \frac{23 - 150}{10} \\ \\ = \frac{ - 127}{10} = - 12.7 \\ \\ \\2.( 1.38 \times10 - 14) \\ \\ = \frac{138}{100} \times 10 - 14 \\ \\ = \frac{138 - 140}{10} = \frac{ - 2}{10} = \frac{ - 1}{5} = - 0.2 \\ \\ \\ \\ so \\ \\ - 0.2 > - 12.7$
