Answer 5

\[\frac{ 6 }{ 6 } = \frac{ 2 }{ 6 } - \frac{ 1 }{ 6 } - x\]

solving for x gives you 1/2

Answer 6

but how do you come with 1/6 or 2/6 if it only mentions 1/3 and 1/6

Answer 7

1/3 + 1/6 + S = 1 where 1/3 of the box is History, 1/6 is English and S is the fractional portion of Science books in the book. The number 1 represent the entire box.

Get a common denominator of 6 for 1/3.

1/3 = ?/6
That would be 2 or 2/6

1/3 + 1/6 + S = 1

2/6 + 1/6 + S = 1

3/6 + S = 1

1/2 + S = 1 Note that 3/6 = 1/2

S = 1 - 1/2

S = ? fraction of the box designated as Science books. @Kfsv10
