Lets make a proportion with the information we know. For every 1000, 8 of tax is paid.
8/1000
Then, use the rest of the information to make another proportion. We don’t know how much the tax is, so let’s call it x.
x/150000
Set the equations equal to each other
8/1000=x/150000
Cross multiply
1000x=1200000
Divide by 1000 on both sides
x=1200
When a number has a negative exponent, that means it's on the wrong side of the fraction bar. So since it is 3^-1 , it is equivalent to 1/3.
So 1/3 is 0.333
And 1/4 is 0.25
1/3 > 1/4
