So the unit rate is 66:1
then you do 66*3=198
198:3
then you do the same thing 66*7=462
462:7
lastly you do 66*15=990
990:15
Answer:
-8.8517
Step-by-step explanation:
We assume you want the log of 462 to a base of 1/2. Using the change of base formula, this is ...

2 * 2 and 3/4.
2 and 3/4 = (4*2 + 3) / 4 = (8 + 3) / 4 = 11 / 4
2 * 11/4 = 22 / 4 = 5 and 2/4
= 5 and 2/4 or 5 and 1/2 or 5.5
Hope this helps.
