正しい英語の使い方コミュのSimple Math

I've thought of this a long time ago and since forgotten about it. Shame on me.

***** Simple Math Questions *****

Here is a 5-liter bottle of olive oil (that I bought at the Sam's Club :)). Each serving is 15 ml, and one serving of this olive oil contains 120 Calories.

Question 1: How many servings of olive oil does this bottle contain?

Question 2: An average active woman requires approximately 2,000 Calories per day to maintain her weight. As soon as the excess caloric intake reaches 3,500 Calories, she would gain 1 lb. In order to gain five pounds in 30 days, how much of this olive oil should she use in cooking on top of her regular 2,000-Calorie diet?

***** These were simple, weren't they? *****

Well, you don't really have to answer the questions ...

Has anyone taken the SAT before? How did you do?

When I first took the SAT, my Japanese was actually better than my English (boy, those were the days!). My SAT score for the English part was rather horrid, to be honest with you ... but the math part was "almost" perfect. It was "almost" because I didn't miss any questions but those that contained terminology that I didn't know or understand.

... Thought it'd be fun to have a thread on math. Got any simple math questions, or any memory regarding the subject? Whether you love it or hate it, you need the darn subject ... :)

Liters? Mililiters? Gee, I forgot all those metric units! 笑

1. 5000 / 15 = 333.3... (repeating), so 333 servings.
2. (3500 x 5) / 120 = 145.83... (repeating) so it takes 146 servings to gain five pounds. 146 / 30 = 4.86... (repeating), so she needs to use approximately 5 servings of the olive oil each day.

Hope I'm correct!

So nobody likes math, I take it. *snicker*

1. That'd be correct, but guess what? The nutrition information label on the bottle actually says 338 ... which bag of bones did the calculation for that, I wonder?

2. I had a slightly different order of calculation in mind, but the rounded number for the answer is the same. And after realizing just how much 5 servings of olive oil is, just thinking about it thoroughly made me sick. (^^;

Now that we got the question-and-answer part out of the way, doesn't anybody have any story about math (trig, calc, algebra, whatever ...) in English at all?

Any story about math... well I've always liked math so I don't have much to tell about myself and math. I *can* tell you how much trouble I go through every day helping my wife with her trig class now, but I don't think she'd appreciate it very much! For instance, it took her a few minutes to understand sin(pi/6) = 1/2.
