15_

which would be 15 with the line underneath it

over 3/4

what does that mean

15 divided by 3/4?


Problem 2

another simple math one for u would be lol



a .05 into a fraction

b .048 into afraction

i dont recall doing this 14 yrs ago

question 3 a covert 34% into a fraction

i think its 1/34

b .0.05 into a fraction

out of 30 thats all i missed

so far i got a 95 average


If anyone can recall how to do them and show me i would appreciate it ;)

1. (15)(1.33) = 20

2. 1/20, 6/125

3. 17/50, do you mean .005? That would be 5/1000 or 1/200.

1. 15/(3/4) = (15*4)/3 = 60/3 = 20

2 a) 0.05 = 5/100 = 1/20

b) 0.048 = 48/1000 = 6/125

3. 34% = 34/100 = 17/50

.0.05? No idea what that means, there can only be one decimal place in a real number. If it's 0.05, then that's the same thing as 2a). Double check your typesetting.

DEPENDS If it's

15
______

3
_
4

then yes, you invert the fraction on the bottom, and multiply it by the top, or

15 x 4/3

BUT If it's

15
__

3
__________

4

then you just drop the 3 down and the fraction becomes

15/ (3x4)

or 15/12

a. .05

it's 1/20

Think of it as 5 cents, or a nickel. A nickel is 1/20 of a dollar

b. .048

if you're ever unsure, just put the decimal into unsimplified form, which means you just write it as a whole number over 10, 100, 1000, or whatever depending on how long it is, always the same number of zeroes as digits, so

.048 = 48/1000

(48 has two digits, 100 has two zeroes)

Now simplify, divide by 2

24/500

divide by two again

12/250

divide by two again

6/125

and that's the answer

c. 34%

always converts percents into decimals first. That's easy, divide by 100. So 34% = .34

now just do the fraction trick

.34 = 34/100

divide by two

17/50

and that's the answer.

15/(3/4) = 15 divided by 3, times 4 = 20 or 15/.75

34% can be written as 34/100

.05 = 1/20

48/1000 = .048

Ok someone can help me with my math homework now:

Prove that in a linear space L, the collection of all sets C which are equal to their core-point sets core(C) generates a topology on L, the core topology. Consider also the case when each C is convex.

Anyone? ;)
