2) Determine which number does not belong on the list. Explain your resoning.

25 5
---- 625% ----- 0.625 62.5%
40 , , 8 , ,

Sorry It was kinda confusing, It messed up!!!!!!!!!!!!!!!!!!!

2)25/40 in a fraction 625%, 5/8 in a fraction, 0.625, and 62.5%..............Hope that helps!!!!

Answer 1

the first one is 5%. 14*10= 140 14=10% 140*2=280 so the percent would be half of 10 percent which is 5%

8 is not divisble by 5 so 8 is the anwser on the second one.

Answer 2

1. set this up as a fraction.

14/280 = x/100 cross multiply to get
280x = 1400 solve the equation
x=5

14 is 5% of 280

2. there are two possible answers for this
a) 8, because the rest are divisible by 5
b) 625%, because the values of the rest are equal in calculatic relation

Answer 3

1) 5%. 14/280X100%=5%.
2) 8. This is a guess, because 8 is the only number in the series that is not divisible by 5.

Answer 4

1. (14/280)*100 ---- 5 %

the second question is not clear ... are you writing three different series or same series in 3 lines

now I understand the question, yes 625% is not same as others, which are all different specification of 62.5%

Thanks Veer

Answer 5

A "percent" is a fraction in hundredth (in Latin, hundred is centum and 14 percent means 14/100

Here you do not know the percent (i.e., the fraction over 100) so use x.

x/100 of 280 = 14

280 * x/100 = 14

one equation, one unknown; go for it.

Answer 6

1) 5%
2) 625%, cause the others are the same

Answer 7

1. General Rule: Is/Of = %/100, so, 14/280 = x/100, solve for x:

x=14*100/280= 5%

2. I don't quite understand what you're saying.

Answer 8

1) 5%
2) too confusing..

Answer 9

1) 14 = n * 280
14/280 = n
.05 = n
5% = n

2) No clue what you are doing.
