how do i solve that? -3 - 7/12
OpenStudy (anonymous):
You got the bit in brackets wrong
OpenStudy (anonymous):
\[1\div3+3\div4\]

Good Lord! I am trying to help my daughter and I do not know how to do it. This is crazy!

why would you divide?
OpenStudy (anonymous):
1/3 means 1 divided by 3
OpenStudy (anonymous):
one third plus three fourths
OpenStudy (anonymous):
Ok 1/3 +3/4 find a common denominator (number on the bottom)
So 3x4=12 so multiply all parts of 1/3 by four and get 4/12
4/12 = 1/3
OpenStudy (anonymous):
do the same with 3/4 and we get 9/12
So 3/4 = 9/12

In brackets the equation is (\[(4+9)\div12\])
OpenStudy (anonymous):
so that would be 13/12 or 1 and 1/12?
OpenStudy (anonymous):
Exactly the same thing...............see it's all coming back ;D
OpenStudy (anonymous):
then what would you get for the answer if -3 - 1 and 1/12?
OpenStudy (anonymous):
Yep, sounds about right to me. That ok?

-3-(1&1/12) equals what?
OpenStudy (anonymous):
thanks for being patient with me. I have not done this stuff in 20 years! (I didn't pay attention much in high school either) lol!
OpenStudy (anonymous):
ok what does -3 -1=?
OpenStudy (anonymous):
-2
OpenStudy (anonymous):
You have -3 and you minus another -1 away you have -4.
But the question ask what does -3-(13/12) or what does :
-3-(1 and 1/12) equal.

OpenStudy (anonymous):
so do you find common denominators
OpenStudy (anonymous):
Yep and they would be?
OpenStudy (anonymous):
answer would be -23 over 12 or -1 and 11 over 12?
OpenStudy (anonymous):
I don't know let's work it out
common denominator is 12 so we h
\[-36+13\div12\]
OpenStudy (anonymous):
which = -23/12 or -1 11/12 as you said
