Negative numbers. Remember that whole numbers are 0 and positive numbers.
If the proportion of iris to roses in Nikki's garden is 2: 5, it means that for 25 roses: (2/5) = (10/25). Therefore to maintain the proportion by adding 20 roses: (2/5) = (18/45). The number of irises after the addition of roses will be 10 + 18 = 28 irises.
Mode is the number that shows up the most
in this case, it is 71,500 which shows up twice, one more than any of the other numbers
hope this helps
