A new coin is worth 3 times the value of the other 17 coins. What value of the total does the new coin represent?
Given that a new coin is worth 3 times the value of the other 17 coins, it represents 13.5 of the total value. To calculate, use the ratio theorem such that 3:1.
I remember when I had homework....
Are the other 17 coins of the same value?
