Well, you're asking for a refresher on multiplying fractions, but then the
example at the end of your question uses the symbol for division, not
multiplication. So I'll just give you the rules for both operations, and let you
choose the one you need.
To multiply fractions:
-- Multiply the two numerators.
Write the product on top of a new fraction.
-- Multiply the two denominators.
Write the product on the bottom of the new fraction.
-- The new fraction is the product of the two original fractions.
To divide fractions:
-- Invert (flip) the second fraction.
-- Then multiply them.
-- Their product is actually the quotient of the two original fractions.
Okay so in a gallon there are 16 cups, in this case 100 cups is equivalent to 6.25 gallons. 6.25 times 3.12= 19.5
Therefore $19.5 is how much the gas cost!

Step-by-step explanation:
cos(x) = 179/202
x = arccos(0.886138613861)
x = 27.608033...
x = 28°
Assuming all the hours are done within the same week, then
normal pay (assuming 40 hours per week) = 40*12 = $480
Overtime pay = $300 = x hours * (12*1.5)
Solve for x:
x=300/(12*1.5) = 300/18 = 16 2/3 hours
