Express the weight of a "Quarter Pounder" in grams, given 2.205 pounds (lb) is equal to 1 kilogram (kg).

The answer here is that a Quarter Pounder weighs about 113
grams.  Here is how we find this answer.

First, we start
with the assumption that a Quarter Pounder is truly .25 of a pound.  Then we find out
how many kilograms are in .25 pounds.  We can do this by setting up the following
equation:

2.205/1 = .25/x

When
we do the math, we will get the answer for how many kilograms are in .25
pounds.

First, we cross multiply and
get

.25 = 2.205x

We then
divide by 2.205 to solve for x and we get

x =
.113

So we know that .25 pounds is .113 kg.  So now to get
to grams, we move the decimal point three places to the right because there are 1000
grams per kilogram.  This gives us 113 grams.

So we know
that .25 pounds is about 113 grams.
