Answer 6

\(\large\frac{5}{60}\rightarrow\frac{1}{12}\)

\(\large\frac{55}{60}\rightarrow\frac{11}{12}\)

\(\Large (\frac{1}{2}+\frac{1}{4}+\frac{1}{4}+2(\frac{1}{12}))-\frac{11}{12}=\tt the~answer\)

Answer 7

so -11/12 or 11/12

Answer 8

@StudyGurl14

Answer 9

What are you talking about?

Answer 10

is it -11/12 or 11/12

Answer 11

Next step:
\(\Large 1+\frac{2}{12}-\frac{11}{12}=\tt the~answer\)

...because \(\large\frac{1}{2}+\frac{1}{4}+\frac{1}{4}=1\)

Answer 12

so what is the answer?

Answer 13

Next Step:
\(\Large 1-\frac{9}{12}=\tt the~answer\)
...because \(\large\frac{2}{12}-\frac{11}{12}=-\frac{9}{12}\)

Answer 14

And since \(\large 1=\frac{12}{12}\)

\(\Large\frac{12}{12}-\frac{9}{12}\rightarrow\frac{3}{12}\rightarrow\frac{1}{4}=\tt{the~answer}\)
