Answer:
A = 0.75 gram or 1 gram
Step-by-step explanation:
The half-life of carbon 14 is years. How much would be left of an original -gram sample after 2,292 years? (To the nearest whole number).
We can use the following formula for half-life of 
to find out how much is left from the original sample after 2,292 years:
where:
<em>A</em> is the amount left of an original gram sample after <em>t</em> years, and
is the amount present at time <em>t</em> = 0.
The half-life of is the time <em>t</em> at which the amount present is one-half the amount at time <em>t </em>= 0.
If 1 gram of is present in a sample,
Solve for A when t = 2,292:
Substituting = 1 gram into the decay equation, and we have:
A = 0.75 g or 1 g
Since its 3/4 serving and there are 18 pancakes
18 divided by 3/4
just find the reciprocal (switch the denominator and numerator) and change divide to multiply
18 x 4/3 = 24 servings
the reason being for multiplying the reciprocal: there is a rule stating that whenever you divide something by a fraction, you change the divide sign to a multiplying sign and flip the flip the digits in the numerator and denominator section in the fraction (basically the fractions reciprocal)
or another way of doing it is
3/4 = 0.75
18/0.75 = 24
but you'll likely to need a calculator for that
