Easy. First of all when you divide a negative by a negative you get a positive.
So just write the question as 7 divided by 1 1/2
Turn your fraction into a decimal (1.5) or an improper fraction (3/2)
So your question is now 7 divided by 3/2.
To divide a fraction, invert the 3/2 and change your sign.
You now have:
7 x 2/3 = 14/3
14/3 = 4 2/3
If I misunderstood your question and you mean:
-7 divided by -1/2, the process is still the same but looks like this:
-7/1 divided by -1/2
-7/1 x- 2/1 = 14/1 or14
You need to know how to divide fractions..the integers thing is easy.
Neg divided by a neg is pos.
Neg divided by a pos, is neg.
Pos divided by a neg, is neg.

answer: 1st attitude= x tiers 2d attitude= 2x tiers third attitude= 3/4 x tiers *sure, sum of all angles is a hundred and eighty for a triangle so as meaning x+2x+3/4x= 3 3/4 x = a hundred and eighty with the intention to get x (which will aid you be sure sizes of the angles), you ought to divide 3 3/4x by ability of nicely, 3 3/4... Which additionally is going for a hundred and eighty on account that as reported above, it truly is comparable to 3 3/4x. to try this, replace 3 3/4 to an fallacious fraction that's 15/4. Now, multiply this is reciprocal or multiplicative inverse (4/15)to a hundred and eighty. e.g. a hundred and eighty x 4/15= x 720/15=x 40 8=x now that all of us understand the cost of x, shall we clean up for the angles solutions: First attitude = 40 8 tiers of course through fact it truly is x... 2d attitude = ninety six tiers through fact it truly is two times x... third attitude= 36 through fact it truly is 3/4x... Now, try including those 3 values to ascertain if those are recommendations-blowing 40 8+ninety six+36= a hundred and eighty nicely, now you have the respond!!! BTW, a seventh grader spoke back this question, yet his from the Philippines and this is summer time right here so he's complete with that direction...
