Answer:
140 coins
Step-by-step explanation:
To calculate the total number of coins Kate have in her collection, we can use the rule of three:
The problem says that 7 of her coins are equivalent of 5% of her entire collection, and we want to know the total number of coins (100%) of her collection. So, if 7 coins are 5%, how much coins are 100%:
7 -> 5%
X -> 100%
7/X = 5/100
X = 100*7/5 = 140 coins
