ANSWER
EXPLANATION
The given vectors are:
and
To find the dot product of the two vectors, we multiply the corresponding components and add them.
This implies that,
Therefore the dot product of the two vectors is 51.
Because 5120 and 1280 are quite large numbers, we can find what is being done in the sequence by looking at 320 and 80, where 320 is being divided by 4. Now that we know that this is process, we can just divide 80 by 4 to get 20, the first missing term, and 20 by 4 to get 5, the second missing term. I hope this helps!

Total number of peaches = 15
Percentage of blank peaches out of the total peaches = 75%
Then
Number of blank peaches out of the total peaches = (75/100) * 15
= (3/4) * 15
= 45/4
= 11 1/4
So 11 1/4 peaches are blank. If you do not want to include the fraction part of the answer, then you can take either 11 or 12 peaches to be blank as well. I hope the procedure is clear enough for you to understand. You can definitely use this simple but effective method for solving similar kind of problems in future.
Always place it out of 9. For example, 0.333= 3/9, or if simplified, 1/3.
0.5555? this will be 5/9.
for the other way around, make it a repeating decimal, such as 4/9, make that 0.444
If it is 33/99, or even 333/999, the rule should be the same.
