He has ZERO fewer than Amy. That's actually another way of saying that he has the same amount as Amy.
since Amy has 5 pears, David also has 5 pears.
You can set up this equation as:

Because remember, 70% is equal to 0.7 and x represents the unknown value. So, let's just solve it:

So,
70% of 120 is 84.
The "mean" of a group of numbers is also called their "average".
To calculate the mean, add up all the numbers, then
divide the sum by the number of items on the list.
Step #1: Addum up: 3+7+2+9+4+7+3+7+5+2 = 49
Step #2: Count the number of items on the list: I count 10 .
Step #3: Divide the sum by the number of items on the list.
49 / 10 = 4.9
The mean (average) of the numbers on that list is 4.9 .
Keeping in mind that 120 days is not even a year, since there are 365 days in a year, exluding leap-years, then 120 days is really 120/365 year.
