Answer 1

Answer 2

Actually, it is too easy :( I don't know how to explain.
OK, let do it as:
Firstly. make all fractions has the same denominator, in this case is 5.
\[\frac{ 2 }{ 5 } ; \frac{ 3 }{ 5 } ; and ; \frac{ 9 }{ 15 } = \frac{ 3*3 }{ 3*5 } = \frac{ 3 }{ 5 }\]

For 3 fractions with same denominator, you just compare to numerator, so the answer is

\[\frac{ 2 }{ 5 } < \frac{ 3 }{ 5 } = \frac{ 3 }{ 5 } or \frac{ 2 }{ 5 } < \frac{ 3 }{ 5 } = \frac{ 9 }{ 15 }\]

Answer 3

If you cut a pie into 5 equal pieces
2/5 means 2 of the 5 pieces
3/5 means 3 of the 5 pieces
which is more 2/5 or 3/5 ?
