Math Percentage Question?

Question

You got 38 out of 50 correct, or 76 % each question is worth 2 points

how would I calculate this? I know this is simple but I am having a brain fart and cant figure it out.

I would suppose 50 questions of which only 38 are correct but how would I get the percent?

thanks I know this is real simple but I can't remember right now thanks

another question

you got 80 out of 100 correct for a %? each question is worth 2 points what percent did you get?

thanks. sorry for the dumb question.

Answer 1

lol you're right, it is easy. Percentage just means "out of 100". So you're taking the fraction where your number correct is the numerator and the total number possible is the denominator (so 38/50), and changing it to its equivalent with 100 as a denominator. Divide 100 by the denominator. 2. Multiply that by the numerator. 2 x 38 = 76. For your second question, 100 is already the denominator. So just restate the numerator. 80%

Answer 2

To convert a fraction to a percentage, you multiply by 100.

If you scored 38 / 50, that is 38 * 100 / 50 = 76%.



80 out of 100 is 80%, provided the questions all score equally. Apply the same principle:

Fraction 80 / 100

Multiply by 100:

80 / 100 * 100 = 80%.

Answer 3

First of all, there is no such thing as a dumb question because you are hopefully trying to learn.



you would put 50 into 38



put 50 into 38 0 times

put 50 into 380 7 times

50 x 7=350 30 R

50 into 300 6 times

50 x 6=300



thus your answer is 0.76 0.76 x 100= 76%



80/100=4/5= 80%

Answer 4

To get the percentage correct divide the number correct by the number of problems. 38/50=76%



For 80 out of 100 it would be 80/100=80%

If each question is 2 points then the grade would be 80*2=160 which is how some grades are given.



If however, you want the maximum score to be 100, to find the value of each question divide the number of point total (100) by the number of questions. 100/100=1 point per question.



for the first test 100/50= 2 points per question

Answer 5

if u got 38 out of 50

we could assume ud get 76 out of 100 right (by doubling)



The method we were taught is make it a fraction and times by 100 so 38/50 x 100.



if you get 80 outta 100 it doesn't matter what each questions worth. cause you got 80%



80/100 x 100

Answer 6

per cent means out of 100; if you multiply a number by 100 you get a percentage.



take a number, say 1/2. Multiply by 100 and you get 50%



If you got 38 out of 40, the percentage is (38/40)*100

Answer 7

38 out of 50 = 76 out of 100 = 76% (76 per cent - 76 every 100)



The way to calculate percentages is to adjust (settle) the total quantity to 100.



Example: 4 out of 20. Multiply both terms by 5 and you'll have

20 out of 100 = 20%



Example: 9 out of 43

43 = 100%

1 = 100/43

9 = 900/43 = 20.93...%



80 out of 100 is 80%

Answer 8

I will do the first one.



You got 38 questions right.



Each question correct is worth 2 points.



So, 38 questions times 2 points = 76%, which is a C+ in college language.



You do the rest.

Answer 9

38 divided by 50

Answer 10

to solve the 1st one you would multiply the numerator and the denominator by 2 and get 76/100 or 76%



80%

Answer 11

ok, let's imagine she paid 'x' for the pc. She offered the pc for a income of 25%. or, x + 25% of x = 60 or, x + (25/one hundred)* x = 60 or, x + (a million/4) * x = 60 or, x (a million + a million/4) = 60 or, x (5/4) = 60 or, x = 60 * 4 / 5 subsequently, x = 40 8 So, Chrissie paid £40 8 for the pc! :)

Answer 12

in the first one, i don't get what you're supposed to figure out





the second question the answer is 40/50 if you want me to elaborate email me...
