Answer:
[tex]0.8\ teaspoon[/tex]
Step-by-step explanation:
Let
x ----> the number of teaspoon
y ---> the number of gallons
we know that
[tex]\frac{x}{y} =\frac{1}{10}[/tex] ---> equation A
For y=8 gal
substitute the value of y in the equation A
so
[tex]\frac{x}{8} =\frac{1}{10}[/tex]
solve for x
[tex]x=\frac{1}{10}(8)[/tex]
[tex]x=0.8\ teaspoon[/tex]
