Final answer:
To find the percentage of dimes in the collection, divide the number of dimes by the total number of coins and multiply by 100.
Step-by-step explanation:
To find the percentage of dimes in the collection, we first need to calculate the total number of coins in the collection. The collection contains 11 nickels, 5 quarters, and 7 dimes, so there are a total of 11 + 5 + 7 = 23 coins.
The percentage of dimes in the collection can be found by dividing the number of dimes by the total number of coins and multiplying by 100. So, (7 / 23) * 100 = 30.4%. Therefore, the percentage of dimes in the collection is approximately 30%.
The student's coin collection contains approximately 30% dimes. This was calculated by dividing the number of dimes in the collection by the total number of coins and then converting this fraction to a percentage.
The subject of the question pertains to percentages in a collection of items. To determine the
percentage of dimes
in the collection, you need to calculate the fraction that dimes contribute to the total number of coins, and then convert this fraction to a percentage. We'll start with the total number of coins, which is 11 (nickels) + 5 (quarters) + 7 (dimes) = 23 coins. So, the fraction of coins that are dimes is 7 (dimes) / 23 (total coins). To convert this to a percentage, simply multiply by 100. Hence, approximately 30.4% of the coins in the collection are dimes. When rounded to the nearest ones place, the percentage will be approximately 30%.
