Answer:
14 coins
Explanation:
To find the number of coins that represent 5% of Salma's collection, you can use the following steps:
1. Convert the percentage to a decimal by dividing it by 100: 5% ÷ 100 = 0.05.
2. Multiply the decimal by the total number of coins in Salma's collection: 0.05 x 280 = 14.
Therefore, 14 coins represent 5% of Salma's collection.
