30% = 30/100 = (30 x 3)/(100 x 3) = 90/300
1/3 = (1 x 100)/(3 x 100) = 100/300
As 90/300 < 100/300
Therefore 30% < 1/3
When you divide something by 3/4, there's no way something can decrease, unless the number is a fraction below 3/4.
Since in Step 2, they divided 27 by 3/4, but ended up with 20 1/4, that means that they got step 2 wrong, because 27 / (3/4) is equal to 27 * 4/3 = 36
(This is because dividing by a fraction is the same thing as multiplying by the reciprocal of the fraction.)
So therefore they got Step 2 wrong.
This is true. Debit card payment is out of your own pocket, while Credit card debt is borrowed money that must be paid back later.

Since we are dealing with infinity of functions, we can do a numerous amount of things:
- Since -sin(x) is a shift from the parent graph sin(x), we can say that -sin(∞) = sin(∞) since sin(x) is an oscillating graph. The values of -sin(x) already have values in sin(x).
- Since sin(x) is an oscillating graph, we can also say that the integral actually equates to undefined, since it will never reach 1 certain value.
