2051 kids were surveyed on how they earn money. 47% said parents gave them money, 32% said allowance, 45% said odd jobs, 26% said parttime jobs, and 11% said fulltime jobs. Estimate the number of teens who made each of the response and then find the actual number of each and compare.

Estimating?
11 percent is ten percent with ten percent of that added..
205+21=226
26 precent is about 1/4, th
510
32 percent is nearly one third..
700
47 percent is half minus half of ten percent of that.
102550=975
Now work out the actual numbers, and compare. 
parents = p
allowance = a
odd jobs = j
part time = h
full time jobs = f
all little less than half are p so about 1000, accurately .47*2051 = 964
about 30% are a so about 600
accurately .32*2051 = 656
j little less than for p so maybe 900
accurately .45 * 2051 = 923
h a little more than 1/4 so around 520
accurately .26*2051 = 533
f a bit more than 1/10 so around 210
accurately .11*2051 = 226
