an assortment of coins contains 20 pennies, 2 nickels and 6 dimes. what percentage of the coins are nickels?
show how is solved ?????????
As Bobpursley showed you earlier:
20 + 2 + 6 = 28
2/28 = 0.071
0.071 * 100 = 7.1%
To find the percentage of the coins that are nickels, you need to divide the number of nickels by the total number of coins and then multiply by 100.
Step-by-step solution:
1. Add up the number of nickels, pennies, and dimes: 2 + 20 + 6 = 28.
2. Divide the number of nickels by the total number of coins: 2 / 28 = 0.071.
3. Multiply the result by 100 to get the percentage: 0.071 * 100 = 7.1%.
Therefore, 7.1% of the coins in the assortment are nickels.
