Answer:

0.9972

Explanation:

The sidereal day has a duration of 23 hours 56 minutes and  4 seconds approximately. The solar day has a duration of 24 hours. We have to convert the previous times to seconds:

Solar day:

[tex]24h*\frac{60min}{1h}*\frac{60s}{1min}=86400\\[/tex]

Sidereal day:

[tex]23h*\frac{60min}{1h}+56min=1436min\\1436min*\frac{60s}{1min}+4s=86164s[/tex]

Now, we calculate the fractional difference:

[tex]\frac{86164s}{86400s}=0.9972[/tex]
