They are the same amount but I'd rather have a trunk half full of dimes because it's more convenient to have less coins than more if they both equal the same.
That would be 19 nickels.
There's no specific answer, except to say that the number of nickels must be even (otherwise the total would end in 5 rather than 0). You could have combinations like50 nickels and no dimes40 nickels and 10 dimes25 dimes and no nickels22 dimes and 6 nickelsand so on. Each one, and many other possibilities, all add up to $2.50
you separate a mixture of nickels and dimes by their weight
You will need at least one nickel. With one nickel you would need 12 dimes to make $1.25. If you have more nickels, then subtract one dime for every two additional nickels you have, so if you have 5 nickels you will need 10 dimes.
You would have 7 nickels and 13 dimes. (7 x $0.10) + (13 x $0.05) = $1.35
The volume of a dime is roughly half the volume of a nickel, so any specific number of dimes would take up about half as much space as the same number of nickels*. In other words, a half a trunk of dimes would have at least the same number of that coin as a full trunk of nickels. However each dime is worth twice as much so the half-trunk of dimes would be worth more. * Because dimes are smaller they'd be able to pack somewhat more tightly than nickels so you could probably get slightly more dimes into the half-trunk. However that doesn't affect the answer; it simply means the half-trunk would be worth even more.
That would be 19 nickels.
111 quarters, zero dimes, zero nickels 110 quarters, two dimes, one nickel 109 quarters, four dimes, two nickels
There must be at least one nickel, to account for the 5 cents of the 75 cents. So, one solution would be 1 nickel and 277 dimes. This would be (277 x 0.10) + 0.05 = 27.70 + 0.05 = 27.75 Another solution would be 1 dime and 553 nickels. This would be (553 x 0.05) + 0.10 = 27.65 + 0.10 = 27.75 You will have an odd number of nickels in an solution. Possible solutions include 1 nickel & 277 dimes 3 nickels & 276 dimes 5 nickels & 275 dimes 7 nickels & 274 dimes 9 nickels & 273 dimes up to 553 nickels and 1 dime

Two nickels equal the value of one dime, therefore fourteen (14) nickels would equal the value of seven (7) dimes.
Ten it each group.
You will need at least one nickel. With one nickel you would need 12 dimes to make $1.25. If you have more nickels, then subtract one dime for every two additional nickels you have, so if you have 5 nickels you will need 10 dimes.
You could have: 8 nickels and 1 penny or 6 nickels and 11 pennies or 4 nickels and 21 pennies or 2 nickels and 31 pennies. The option of 0 nickels and 41 pennies is excluded by the necessity that the amount is made up of dimes, nickels and pennies; 0 nickels would mean the $1.21 was made up of dimes and pennies only.
well if a dimes 10 and a nickels 5 the answer would be 9.. UK here pence and pounds
A US nickel is 5 cents, so convert the dimes and quarters to multiples of 5: One dime is 10 cents or 2 nickels, so 9 dimes would be equivalent to 18 nickels. A quarter is 25 cents or 5 nickels, so 6 quarters is 30 nickels.
