Answer 6

I might be wrong but...
does 20 times 125% equal 25?
if yes, then he is correct :)

Answer 7

ok thanks!

Answer 8

yay! ur here!

Answer 9

have you done this before?

Answer 10

Ok so how I'm going to do my answer is similar to jiggles. I've had a similar question on one of my tests and got it right. So first of all there are many ways to doing this problem. A way could be multiplying hours to get the percentige. So multiply 20 by 25 and see what you get I may be wrong but just try it.

Answer 11

500

Answer 12

hmmm? if anything I would have thought it would be
does 25 divided by 20 = 125% ?
if it does then he is correct

Answer 13

Ok so was it right? I'm testing you.

Answer 14

no, 25 divided by 20 would be 1.25 not 125%.

Answer 15

Yes jiggle I'm testing her. She needs to be able to understand the problem before continuing to get the answer.

Answer 16

How do you normally figure out a problem like this?

Answer 17

@77777jeannie77777 what is 1.25 as a percent? :)

Answer 18

Jiggle would you like to explain to her how to do this problem.

Answer 19

i dunno. im not sure

Answer 20

Jiggle I just did the problem and your way wasn't quite accurate I got 0.8.

Answer 21

@FelicitySchimke you did 20/25
I said to do 25/20

Answer 22

so then can someone tell me the answer? or at least how to solve the problem?

Answer 23

How did you get your answer Jeannie? I realize that jiggle thank you. We cannot give you the direct answer.

Answer 24

I basically told you the answer @77777jeannie77777 :P
does 20 times 125% equal 25?
if yes, then he is correct :)

Answer 25

oh, then he is correct. can you show me how to "show my work for the problem"?

Answer 26

Yes jiggle your way is more accurate but next time would please not give her the answer. Bye!

Answer 27

because i have to show my work or ill get it wrong

Answer 28

bye

Answer 29

@FelicitySchimke I did not really give the answer, jeannie had to do the calculation herself in

Answer 30

yeah thats true

Answer 31

but how do i "show my work?"

Answer 32

I am personally horrible at "showing my work" :/
usually I would just put the math I did and say "since the statement is true, Evan is correct"

Answer 33

so then would this be good? "Evan's work is correct; I know this because 20 x 125% = 25."

Answer 34

just put something like 25/20=1.25 convert to percent = 125%

Answer 35

oh, ok. thanks you guys! even though i was a little confused at first, i get it now!you guys did great! :D

Answer 36

glad we could help :)

Answer 37

:D

Answer 38

bye!
