2 half dollars just mean a dollar. In that case, that's 10 dimes. (10*10=100)
Answer:
10 dimes
Step-by-step explanation:
So in order to get this answer we first must know that...
1 half dollar = 50 cents
1 dime = 10 cents
So...
5 dimes = 50 cents
2 half dollars = 100 cents aka $1
10 dime = 100 cents aka $1
Therefore we can use our common sense to figure out that 2 half dollars is 10 dimes.
