Let the number of nickels be = n
Let the number of dimes be = d
Let the number of quarter be = q
Total money William has = $12.80
As given, there are 3 times as many quarters as nickels

And 20 more dimes than nickels

As total money is $12.80

Putting the values of 'q' and 'd' to find 'n'





Hence the number of nickels are = 12
If you want to also find dime and quarter, then

One bag would be 2.7 kg. If you equally pour 8 kg of oats into 3 bags, you divide 8 by 3 which gets you 2.666666666666667 (rounded to one decimal place is 2.7, it depends to what decimal place the question asks you to round your answer to).
