Answer: 3/5
Step-by-step explanation: To find the reciprocal of 1 and 2/3, we first need to convert 1 and 2/3 to an improper fraction.
To write a mixed number as an improper fraction, first multiply the denominator times the whole number, then add the numerator.
So here, we multiply the denominator, 3, times the whole number, 1, then we add the numerator. So we have (3 x 1) + 2 or 3 + 2 which is 5.
Now we put our new number over our old denominator and we get 5/3.
However, we're not done yet. We still need to find the reciprocal.
The reciprocal describes a fraction so when we're asked to find the reciprocal of 5/3, we want to switch the numerator and denominator.
So if we switch 5/3, we get the proper fraction 3/5.
Therefore, the mixed number 1 and 2/3 is equivalent to the improper fraction 5/3, and if we switch the top and bottom numbers, we get 3/5.

Alright, so the population of the herd is 220 in 2012. This means that when it decreased by 10 percent in 2014, 10 percent of the population is taken away. To find 10 percent of the population, we simply multiply 220 by 0.1 due to that to get a percentage as a decimal, we simply divide the percentage amount by 100. In addition, as the elk population in 2012 represents 100% of the elk population that we’re starting with (100%=1, or the whole thing), 10% subtracted from 100% is 90% of the population, or 220*0.9 as the population in 2013. To get the population in 2014, we have to multiply the population in 2013 by 0.9 similar to how we got from 2012 to 2013. This means we multiply (220*0.9)*0.9=178.2, which rounds down to 178 as the next number, 2, is less than 5. If that 2 were to be 5 or higher, we would round up to 179.
