help me please complete the table at the right by writing the fraction of the day each animal sleeps and an equivalent fraction

finlep [7]

Answer:

1 day = 24 hours

Divide each of the "number of hours spent sleeping" by the total number of hours in a day (24). Then divide the numerator and denominator by the highes common factor to reduce the fraction to its simplest equivalent.

$\sf Cat=\dfrac{12}{24}=\dfrac{12 \div 12}{24 \div 12}=\dfrac{1}{2}$
