Math Help!
I have a quiz tomorrow in math and I dont know really understand how to find something from a cirle graph. Okay so lets say that the cirle graph is called Persons Living Alone by Age and the pieces of the cirlce are ages45-64 is 33.4% Ages 25-44 is 14.8% and Ages 65 and older is 46.7%. Lets say they ask If the total of 10,851,000 people were living alone, how many in each age group were living alone? How do I find it out? Please help and thank you! Sorry its so long!

multiply the percent by the total number like 10,851,000 multiplyed by .334 eqauls the answer for age group 45-64

For your information, the three parts of your pie chart don't even come close to adding up to 100%. They only add up to 94.9%.
Multiply the percentage in decimal format by the total number of people. I'll do "Ages 65 and older" as an example.
46.7% = .467
.467 * 10,851,000 people = 5,067,417 people that are Ages 65 and older
Piece of cake (or in this case, pie), no?

you do x over 100 = is over of. so for example,
for ages 45-64, 33.4% out of 100% = x out of 10,851,000. you would then divide 33.4 by 100 then multiply times 10,851,000 and that would be your answer.
you would do the same equation for the rest, you would just replace 33.4% with either 14.8% or 46.7%.
hope i helped!!
