The mass of the quarter is 6 grams. The collection of quarters total 3kilograms. how many quarters are in the collection

Im not 100% sure but there should be 500 quarters

Step-by-step explanation:

to make 1 kilograms you need 1000 grams 1 quarter weights 6 grams according to the problem so 1000:6 will equal how many quarters there are in 1 kilogram so then multiply by 3 as there are 3 kilograms and you get 500

sorry im absolutely bad at explaining
