198/27+6(2+8(1-2)+(11-3)+5)/2=28

How and why?

This is false

$$\frac{198}{27}+\frac{6(2+8(1-2)+(11-3)+5)}{2}$$

$$=\frac{198}{27}+\frac{6\cdot(2+8\cdot-1+8+5)}{2}$$

$$=\frac{198}{27}+\frac{6\cdot7}{2}$$

$$=\frac{22}{3}+\frac{6\cdot7}{2}$$

$$=\frac{22}{3}+\frac{42}{2}$$

$$=\frac{85}{3}$$

$$=28 \frac{1}{3}$$

Hope this helped!

Hmm.. Maybe they just rounded it? Or you typed in the question wrong?

According to Wolframalpha, it's 28 1/3, and when I solved it I got the same thing.

Hi tacobell, I think that Violynx is correct.
