To solve this all you need to do is take the fraction 2/5 and multiply it by a number (this means you multiply BOTH the denominator and the numerator)
1. Multiply the original fraction by 2:
[tex]\frac{2*2}{5*2} = \frac{4}{10}[/tex]
2. Multiply the original fraction by 3:
[tex]\frac{2*3}{5*3} = \frac{6}{15}[/tex]
3. Multiply the original fraction by 4:
[tex]\frac{2*4}{5*4} = \frac{8}{20}[/tex]
4. Multiply the original fraction by 5:
[tex]\frac{2*5}{5*5} = \frac{10}{25}[/tex]
5. Multiply the original fraction by 6:
[tex]\frac{2*6}{5*6} = \frac{12}{30}[/tex]
All of the fractions above are equal to 2/5 and to each other. You can keep doing this with higher numbers if you wold like, but these are just a few examples.
Hope this helped!
