We must compute the following quotient:
[tex]\frac{150}{250}\text{.}[/tex]We can write 150 and 250 in the following way:
[tex]\begin{gathered} 150=50\cdot3, \\ 250=50\cdot5. \end{gathered}[/tex]Replacing these values in the quotient, we have:
[tex]\frac{150}{250}=\frac{50\cdot3}{50\cdot5}\text{.}[/tex]Cancelling the 50 in the numerator and denominator we get:
[tex]\frac{150}{250}=\frac{3}{5}[/tex]Answer: 3/5
