Answer:
Let's calculate each of these ratios:
The ratio of 4 dimes to 5 nickels:
Ratio = (Number of dimes) / (Number of nickels)
Ratio = 4 / 5
So, the ratio of 4 dimes to 5 nickels is 4/5.
The ratio of 4 dimes to all 9 coins:
Ratio = (Number of dimes) / (Total number of coins)
Ratio = 4 / 9
So, the ratio of 4 dimes to all 9 coins is 4/9.
The ratio of 5 nickels to 4 dimes:
Ratio = (Number of nickels) / (Number of dimes)
Ratio = 5 / 4
So, the ratio of 5 nickels to 4 dimes is 5/4.
