Determine the value of the expression 4/7 of 28

OpenStudy (ja1):

First of all let's see if we can divide 28 by 7...can we?

OpenStudy (anonymous):

you get 4

OpenStudy (anonymous):

i don't understand what they mean by "of"

OpenStudy (jdoe0001):

if we divide 28 in 7 equal pieces, how much is each piece? whatever amount each of the 7 pieces are, it then says grab 4 of those 7 pieces

OpenStudy (jdoe0001):

sorta like grabbing a PIE and cutting it in 7 equal pieces, then taking out 4 of them in this case it's just not a pie, is a quantity :)

OpenStudy (ja1):

Ok so sorry I was afk anyways yes as jdoe is explaining you divide it by 7 and take those four "pieces"

OpenStudy (anonymous):

so is the answer just 4?

OpenStudy (ja1):

We know that 28/7 = 4

OpenStudy (ja1):

No

OpenStudy (anonymous):

okay

OpenStudy (ja1):

First we divided the whole number (28) by the denominator (7) and now we have to multiply the quotient (outcome of dividing) by the numerator.

OpenStudy (jdoe0001):

sammysweets have you done fractions divisions yet?

OpenStudy (anonymous):

i'm sorry, i'm horrible with fractions... so you multiply 4 by the numerator which is 7...?

OpenStudy (anonymous):

no nevermind that's wrong

OpenStudy (ja1):

Remember this little tip, denominator is the number on the bottom and the numerator is on top :)

OpenStudy (anonymous):

would it be 16?

OpenStudy (ja1):

DING DING DING DING

OpenStudy (ja1):

:D

OpenStudy (anonymous):

OpenStudy (ja1):

Haha yes it's simple but you are like me, always over thinking ;)
