second one: republicans under 30 is 196. divide it by the answer of first question. and then multiply by 100

- Howard-Wolowitz

ok so : 1st bottom row 459
2nd bottom row 420
3rd bottom row 231
then going down
1st side row 423
2nd side row 341
3rd side row 346

- Howard-Wolowitz

ok so i got the values but i dont get what i put as the first answer

- Michele_Laino

total republican are:
\(196+120+143=...\), so the requested percentage, is:
\[\frac{{30}}{{196 + 120 + 143}} \cdot 100 = ...\% \]

- Howard-Wolowitz

Sorry I have made an error, here are the right percentages:
Republicans: 42.70%
Democrats: 32.85%
Independent: 38.53%

- Michele_Laino

hint:
what is: \(42.7+32.85+38.53=...?\)
namely the sum of the above percentages

- Howard-Wolowitz

114.08

- Michele_Laino

is it possible to get a percentage greater than 100 % ?

- Howard-Wolowitz

no but thats what that add up to?

- Howard-Wolowitz

am i not right?

- Michele_Laino

please wait...

- Howard-Wolowitz

ok

- Michele_Laino

we have 423 people under 30, and so we get the subsequent percentages:
percentage of republicans people under 30 is: \((196/423)⋅100=...\%\)
percentage of democrats people under 30 is: \((138/423)⋅100=...\%\)
percentage of independent people under 30 is: \((89/423)⋅100=...\% \)

- Michele_Laino

I think that it is what we can say about political party for people under 30

- Howard-Wolowitz

were gonna be getting decimals here

- Howard-Wolowitz

the first one is 46.33

- Michele_Laino

please keep in mind that they are percentages

- Michele_Laino

correct!

- Howard-Wolowitz

so basically 42.70% is wrong for the answer? of my second question and the correct answer is 46.33%

- Howard-Wolowitz

doing these how are we gonna gt the answer to this

- Michele_Laino

please note that the first percentages refer to whole people, whereas the second ones refer to people under 30

- Michele_Laino

oops.. refer to all people not whole people

- Howard-Wolowitz

ok i see .. again im sorry but i am confusing myself here

- Michele_Laino

furthermore, we can observe this:
since the first percentage about democrats is 32.85, whereas the second percentage is 32.6, then we can say that democrats party is composed by almost people under 30

- Michele_Laino

namely the major part of democrats people is under 30

- Howard-Wolowitz

so your saying that it would be major part of democarts is under 30

- Michele_Laino

yes!

- Howard-Wolowitz

do you think that my teacher would understand that for an answer?

- Michele_Laino

I think so, since it is logically correct!

- Howard-Wolowitz

ok sweet.

- Michele_Laino

ok! :)
