7 0

Answer:

8.1 * 10^-2

Step-by-step explanation:

Scientific notation is a number with it's largest digit in the one's place and its succeeding digits following it as decimals, then multiplied by a power of ten.

Appling this knowledge to the given number, we can conclude:

0.0810

= 0.081

= 8.1 * (1/10) * (1/10)

= 8.1 * 10^-1 * 10^-1

=9.1 * 10^-2

Half of 2/3 is:

$\frac { 1 }{ 2 } \times \frac { 2 }{ 3 } =\frac { 1 }{ 3 }$

This means that 1/3 was left. This also means that they ate 1/3 of the lasagne.
