I'm doing the same thing right now and I'm lost.
its d, I just solved it...
2.161616 = 2.161616/1 =21. 61616/10 = 216.1616/100 = 2161.616/1,000
= 21616.16/10,000 = 216161.6/100,000 = 2161616/1,000,000
As a mixed number = 2(161616/100,000)
capital A
lower case and upper case v
lower case and upper case o
lower case and upper case i
lower and upper case w
A/3=7/10
21=10a
a=2.1
100a=100*2.1=210
