Answer:
If the signs of rational numbers are same, then the answer is positive.
If the signs of rational numbers are different, then the answer is negative.
Step-by-step explanation:
Consider the provided information.
A: When multiplying or dividing rational numbers, when will the answer be positive?
If we are multiplying or dividing rational numbers the answer will be positive if and only if both the rational numbers have same sign.
For example: Multiply 2 and 4.
2×4=8 (same sign)
or
Multiply -2 and -4.
-2×-4=8 (same sign)
8 is a positive rational number.
Now divided 2 and 4.
or
Divided -2 and -4.
1/2 is a positive rational number.
Hence, If the signs of rational numbers are same, then the answer is positive.
B: When multiplying or dividing rational numbers, when will the answer be negative?
If we are multiplying or dividing rational numbers the answer will be negative if and only if both the rational numbers have different sign.
For example: Multiply 2 and -4.
2×-4=-8 (different sign)
or
Multiply -2 and 4.
-2×4=-8 (different sign)
-8 is a negative rational number.
Now divided 2 and -4.
or
Divided -2 and 4.
-1/2 is a negative rational number
Hence, If the signs of rational numbers are different, then the answer is negative.
Answer:
In a 1000 days Mercury will make 8.624 more revolutions than Earth!
Step-by-step explanation:
<u>Earth</u> takes 365 days to make a complete revolution.
we can say that the rotational speed of Earth is
so, in a 1000 days how many revolutions will Earth have made?
see that the 'day's cancel out. Simply multiply the two numbers!
<u>Next, do the same for Mercury</u>
we can say that the rotational speed of Mercury is
as it completes 1 revolution in 88 days.
so, in a 1000 days how many revolutions will Mercury have made?
multiplying by 1/88 by 1000 yields:
The Question is how many MORE complete revolutions will Mercury make in 1000 days?
We need to subtract the revolutions of Mercury with Earth to find how far ahead is Mercury from Earth
In a 1000 days Mercury will make 8.624 more revolutions than Earth!
