This is so confusing...
Ainat [17]
It's less confusing if you only think about one of them at a time.

A).
Change the whole thing to all inches.
(Multiply the 8-ft by  12inches/foot.)
Then, when you have it all in one number of inches,
multiply that number of inches by  (2.54 centimeters/inch).

B).
1 ounce is the weight of 28.35 grams (on Earth).
Multiply the 300g by  (1 ounce / 28.35 g).

C).
Multiply the liters by (0.264 gallon/liter)
Multiply the km by (1 mile / 1.609 km).
Then you'll have a fraction that actually means
                 (a number of gallons) divided by (a number of miles).
Do the division, and you'll have the gallons per mile.

D).
The area of any rectangle is (length) times (width).
The area of this living room is (13-ft times 14-ft), and that's in square feet.
You know how much 1 square foot of carpet costs.
Just multiply that price by the number of square feet that you need.

Alexeev081 [22]

Answer:

Choice B) No.

Step-by-step explanation:

When she starts , she does a sit-up every 222 seconds.

But as she gets tired, each sit-up takes longer and longer to do.

It means, each sit-up takes more time than she did at beginning.

So, it is NOT proportional to the time.

If it is proportional, she should take constant number of sit-ups even she get tired.
