Answer:
Only 1st option Negative three-fourths divided by Negative two-thirds has positive quotient.
Option A is correct.
Step-by-step explanation:
We will solve to find out Which expression has a positive quotient.
We know the division rule:
and 
We will use these rules
1) Negative three-fourths divided by Negative two-thirds

The quotient is positive.
2) Negative StartFraction 1 over 8 EndFraction divided by 3 and one-fifth

The quotient is negative.
3) 2 and StartFraction 2 over 7 EndFraction divided by negative one-fifth

The quotient is negative.
4) Negative 6 divided by Five-thirds

The quotient is negative.
So, only 1st option Negative three-fourths divided by Negative two-thirds has positive quotient.
Option A is correct.
We have to find the GCD between 10, 16 and 4 and between x^5, x^4 and x^2
GCD (10,16,4) = 2
GCD (x^5,x^4,x^2) = x^2
So we divide all terms for 2x^2
Final result: 2x^2(5x^3-8x^2+2)
Answer:
Rule 3
Step-by-step explanation:
The values correspond to the equation y=3^x
Answer:
.001
Step-by-step explanation:
You see it is the same numbers just it was moved 3 places to the left.
So the you would multiply it by .001 <------ there are 3 decimal places.
When you multiply them you get.
647.6*.001= .6476
Partial products are the products obtained during the intermediate stages in order to complete a multiplication process.
Consider 68
43, we have to determine the partial products in this.
Now, 
Expanding this, we get

= 
= 2400 + 180 + 320 + 24
= 2924
Hence,
and
are the required partial products in the product of 68 and 43.
So, Option 3 and 4 are the correct answers.
