Question

Can someone help me make percentages in a chart? Please, I really need help!

Answer 1

Suppose you want to show a percentage breakdown of average annual earthquakes in Alaska since 1900. Use the data below to create a pie graph. You will need to convert the number of earthquakes to a percentage of the total number in each case. Use the third column to record the percentages. Add a title to your pie graph. Upload your pie graph.

Answer 2

I will make the pie graph, but I am having trouble finding the percentages...

Answer 3

add them..90 + 20 + 5 + 1 = 116 earthquakes

4 to 5 ---- 90 ----90/116 = 0.775 = 77.5% or if you need to round 78%
5 to 6 ----20 -----20/116 = 0.172 = 17.2 or if rounded = 17%
6 to 7 ---5-------5/116 = .043 = 4.3%
7 or higher --1----1/116 = .0086 = 0.86%

Answer 4

See, that's what I was thinking of, but I wasn't sure about doing it or not, like dividing everything. But okay, So now I understand and I can make the pie graph!

Answer 5

or, like I said, if you need to round them..
77.5 = 78%
17.2 = 17%
4.3 = 4%
0.86 = 1%
-------total 100%
