A dime's mass is 2.268 grams and is worth 10 cents.
A quarter's mass 5.670 grams and is worth 25 cents.
a pound of quarters is theoretically worth the same as a pound of dimes. But there is a cutoff that must be reached because we cannot have fractions of coins... <span>Quarters are vastly more useful, so</span> I would prefer the quarters to dimes :)

1000 chicken wings weighs 3000 g how many grams in one chicken wing weigh
PtichkaEL [24]

Answer:

3 grams are in one chicken wing

Step-by-step explanation:

Set up an equation:

Variable x = grams per 1 chicken wing

1000/3000 = 1/x

Cross multiply

1000 × x = 3000 × 1

1000x = 3000

Divide both sides by 1000 to isolate the variable x

x = 3
