(5x2) / 6x0
10 / 0
The answer is 0
As a rule , - times - = + and - times + = -

Therefore the correct answer to the question is 2m squared n
let h= history books
science books = s
h=2s there are 2 times as many history as science so to get them equal we double the science
h+s=81 there are 81 total history and science books
2s+s=81 substitute 2s for h in the above equation
3s = 81 combine like terms
s = 27
There are 27 science books
h=2s
h=2(27)
h=54
there are 54 history books
