Ann had 45 fliers to post around town. Last week, she posted 2/3 of them. This week, she posted 4/5 of the remaining fliers. How many fliers has she still not posted? i got 6 3/4 but it said i was wrong :(
24 is that right?
So the first week she posted 45 (2/3) or 30 of them and had 15 left. This week she posted 15 (4/5) of them so had 12 left.
So, 1/3 of the posters were not originally posted. Then, 1/5 of the remaining 1/3 were not posted. So, 1/5 of 1/3 is 1/15. 45/15 = 3.
oops I meant 3 left
THREE. :3
12 is the right answer I am pretty sure
three was right! :) i cant get this one either. There are 75 students in a speech contest. Yesterday, 1/5 of them gave their speeches. Today, 1/3 of the remaining students gave their speeches. How many students still haven't given their speeches?
Again 75 total and 1/5 gave their speech -> 75 * 1/5 = 15 60 were left (75 - 15) 60 and 1/3 gave their speech -> 60 * 1/3 = 20 40 left (60 - 20)
1/5 of them were omitted the first time. 1/3 of the 1/5 then gave speeches. 1/5 of 1/3 is 1/15, again. 75/15 = 5.
** who have given their speech...then 75 - 5 = 7- students.
*** ugh, stupid keyboard...70.
40?
it said 70 was wrong.
Wow, I completely screwed that problem up..:P sorry, I was distracted xD
awkward... looks like TBates beat you too it
40 is what it should be.
Stfu Chad.
haha sorry...
great then what would this one be?? There are 90 new houses being built in a neighborhood. Last month, 1/3 of them were sold. This month, 1/6 of the remaining houses were sold. How many houses are left to be sold?
this one i'll try
50!
45..
She needs more than to just be told the answer. 1/3 of the 90 houses were sold, leaving 60. 1/6 of the 60 were sold, leaving 50. That's how Chad got his answer.
i got 50
Sh*t.
tbates am i right?
You are!
ok just because he has a giant green "pi" as his picture doesnt mean he is better than us at math...
"You are!"
lol he has just been right every time i've asked him. no offense!!! :)
