Question

My piggy bank has only nickels, dimes, and dollar bills. The ratio of nickels to dimes is 2:3, and the ratio of dimes to dollar bills is 8:1. What is the ratio of coins to dollar bills?
A 40:3
b 16:3
c 13:1
d 5:1

Answer 1

n : d = 2:3 = 16 : 24
d : bills = 8:1 = 24 : 3

n : d : bills = 16:24:3

coins : bills = (16+24) : 3 = 40 : 3
