PinkGlitterz:

Like this?: 9/(1-7)/11..... Like / as in dividing right?

lock:

the question is 9/1 - 7/11

PinkGlitterz:

Yes but do these ( / ) mean dividing in your equation?

lock:

yes fraction symbol

PinkGlitterz:

ok

jhonyy9:

lock how you assum or subtract two fractions with different denominator ?

lock:

no my common deno is 11 right?

jhonyy9:

yes exactly

lock:

jhonyy9:

what is the next step ?

lock:

subtracting the top?

jhonyy9:

no

lock:

o

jhonyy9:

9/1 bc. 11 is denominator common so what you need to do with 9/1 ?

lock:

multiplyt the top and stuff

jhonyy9:

how you get from 1 the comon denominator ?

PinkGlitterz:

SO basically, Use PEMDAS. P: 9/(1-7)/11 = 9/-6/11 E: none M: none D: 9/-6/11 = 1.5/11 = -0.1363... Not sure if you were looking for a fraction or a simplified number but here ya go.

lock:

the question originaally was 9-7/11 but i added the one under the 9

jhonyy9:

yes you made it right

PinkGlitterz:

Oh ok.

lock:

and then ? what do i do

lock:

how is the calc giving me 8 4/11

jhonyy9:

bc. 11 is common denominator and 9/1 has denominator 1 so you need multiplie this by 11 yes ?

PinkGlitterz:

jhonyy9:

lock:

yes

jhonyy9:

so then how many you will write in the place of ,,?" ?

lock:

jhonyy9:

lock:

jhonyy9:

lock:

to be honest i understood nothing

jhonyy9:

looke please 92/11 = 88/11 + 4/11 yes ? bc. 88+4=92 so but 88/11 =8 => 8 4/11 do you understand it now ?
