Question

will someone explain to me why -2 1/3 +3 1/4= 11/12

Answer 1

hmm what's there to explain?

Answer 2

when you make -2 1/3 why is it -7/3 and not -6?

Answer 3

*-6/3

Answer 4

lol that question didn't make sense

Answer 5

the negative IN FRONT of the fraction
applies NOT just to the 2 after it, but to the whole fraction

\(-2\frac{1}{3}+3\frac{1}{4}=\cfrac{11}{12}\qquad
\begin{cases}
-2\frac{1}{3}\implies \cfrac{-(2\cdot 3+1)}{3}\implies \cfrac{-7}{3}\\
3\frac{1}{4}\implies \cfrac{3\cdot 4+1}{4}\implies \cfrac{13}{4}
\end{cases}\)

Answer 6

oh ok thank you!

Answer 7

\(-2\frac{1}{3}\iff -\left( 2\frac{1}{3} \right)\)
