Neptune completes 1 1/2 turns about its axis each day. How many turns does it complete in 1 week?

7 days in a week, so 7 * 3/2 = ___

To calculate how many turns Neptune completes in 1 week, we need to figure out how many turns it completes in 1 day and then multiply that by the number of days in a week.

We know that Neptune completes 1 1/2 turns about its axis each day. To convert this into a fraction, we can write it as 3/2 turns per day.

Now, we need to multiply this by the number of days in a week, which is 7.

(3/2) turns/day * 7 days/week = 21/2 turns/week

So, Neptune completes 21/2 turns in 1 week.
