If 34.5, 18.2, and 2.6=100%, what is the percentage of each number

please explain

It's asking for the percent that all of the individual numbers according to the total. That means you need to take the total sum of all of these numbers and divide each individual number by that total:

34.5+18.2+2.6=55.3

So now you would divide each number by 55.3:
34.5/55.3=0.6238...
34.5 accounts for 62.4% of the sum.

18.2/55.3=0.3291...
18.2 accounts for 32.9% of the sum.

2.6/55.3=0.0470...
2.6 accounts for 4.7% of the sum.

So once again, 34.5 is 62.4%, 18.2 is 32.9%, and 2.6 is 4.7%. Hope this helps.

34.5 + 18.2 + 2.6 = 55.3.......

55.3 is your number, and the whole of something is 100%....
you need to find out what % of 55.3 is 34.5......what % of 55.3 is 18.2...and what % of 55.3 is 2.6...see below...

To find what percent a certain number is, do this=

34.5 / 55.3 = 0.623869801, then move the decimal 2 places, or 62 %
18.2 / 55.3 = 0.329113924, or 33 % (round .329 up to .33)
2.6 / 55.3 = 0.0470162749, or 5 % (round 4.7 up to 5)

34.5 + 18.2 + 2.6 = 55.3

So multiply each number by 100/55.3

62.39% + 32.91% + 4.70% = 100 %
