Question

Kate has a coin collection. She keeps 7 of the coins in a box witch is only 5%of her entire collection. What is the total number of coins in Kate's coin collection

Answer 1

140 coins total

Explanation:

Straightforward, this reads "7 is 5% of how many?". Algebraically, the word "is" means an equals sign, and the word "of" means you multiply. Of course, the 5% needs to be in decimal form. Taking the sentence above, algebraically it is: 7 = .05x. Divide by .05 on both sides to get x = 140
