what are 5 fractions for 75%

hello?

hello

well, ok, will start you off, what is 75%?

as a fraction

trust me - I know you want to get this done, but it will be much faster to learn it

2 out of 3?

well, so when you see a %, you can start by thinking how many out of a 100

so 75% is 75/100

wait wait 3 out of 4

so if I say 75% of people love fractions, exactly!

yes 3/4 is 75%

and by definition, 75/100 is 75%

so you can follow the same strategy as before

you can either start at 75/100 and reduce

by reduce I mean you can evenly divide both the top and bottom by the same number

or you can start at 3/4 and multiply

ok

so go ahead and try, and I'll check it for you

but on a conceptual level - 75% basically means out of say 100 people, 75 people will do X

wait what do i multiply

well, just like last time, you started with 2/3

and multiplied it by 2/2-6/6

you can start at 3/4, and multiply by 2/2 - 6/6

now the reason you can do this, is because 2/2, 3/3, 4/4, 5/5, 6/6, they're all actually equal to 1

k

and multiplying ANYTHING by 1, gets the same basic thing (hence "equivalent")

so you're really just multiplying by 1 in different but "equivalent" ways

1.6/8

correct

yay

=)

um so the next one would be 3/4 and 3/3

hmmm, well, those are not equal to 1

3/4 is 75%

or .75

it's only equivalent if you multiply the original fraction by 1

since 2x1 = 2, 3x1 = 3 etc... anything multiplied by 1 = 1

now fraction wise, the definition of "1" is something divided by itself

so 1/1, 2/2, 3/3, 4/4, 5/5....

those are all equal to 1

and so if you multiple the original fraction by any of those, you'll have an equivalent fraction (since you've just multiplied by 1)

but it may look different, since there are bigger numbers on the top and the bottom

so the first one you did was correct, you multiplied by 2/2

now you want to multiply by 3/3 and on

so i multiply 3/4 and 3/3

oh sorry lol

I was still stuck on the last question

which was 2/3

yes!

you are in fact right haha

sorry =)

its ok

9/12!

yes! =)

yay

and ps, you can check these by plugging them into your calculator

3/4 and 4/4

75% can also be written as .75

because 75/100 is .75

(move the decimal places two to the left)

so every fraction you give me, if you put it in your calculator and divide, should equal .75

the next answer is 12/16

correct =)

wow lol=)

so if you divide 12 by 16 in your calculator, you will get .75

thats incredible

it makes a lot of sense once you practice =). and that's when math starts getting fun - once it finally makes sense

so keep going =)

ok

15/20!!!

mhmm =)

good work!

ok now can u help me with 60%

ok sure, and it's important you learn the other side of fractions, reduction

meaning you start with a big fraction, and then reduce it to equivalent fractions (make the numbers smaller)

so 75% - we said a basic definition of that is 75/100

as in if 75% of people like football, 75/100 people like football

so what is 60%?

3/5 is 60%

that is definitely true =)

ok so let's do this systematically

65% is the same thing as .65

sorry lol

60% is the same thing as .6

which is the same thing as .6/1

ok but that's not even numbers

but remember what we can do to fractions to get equivalent fractions

multiply by 1

so in this case, we want to get rid of the decimal place

since fractions don't have decimals (in this context)

so let's multiple by 10/10

ok

which will move each decimal point by one place (since it's one zero in 10)

you know i owe you big time for this

it's ok! I've been there, just learned this last year

so .6/1 x 10/10 = (.6 x 10)/ (1 x 10)

so we know that 60% - which is the same thing as .6 , actually equals 6/10
