5 squares of 128 didn't get water.
If 40kg are spread out throughout the entire yard, how much in kilograms of seeds will not be watered?
Use a rule of three to solve the question:
[tex]\begin{gathered} x=\frac{40\cdot5}{128} \\ \\ x=\frac{200}{128} \\ \\ x=1.56 \end{gathered}[/tex]Then, 1.56 kilograms of seeds will not be watered
