i am a mixed decimal number the sum of my whole number is equal to the sum of my decimal number. my tenths is half of my hundredths and my ones is twice my tenths. if all my digit are even and my hundredths is 8 what number am i. pls. answer my question tnx

Assume that the number is AB.CD
sum of my whole number is equal to the sum of my decimal number
A+B=C+D
my tenths is half of my hundredths
2C=D
my ones is twice my tenths
2B=A
my hundredths is 8
D=8
so from 2C=D, C=4
A+B=C+D=4+8=12
A+B=12 and 2B=A
2B+B=12 so B=4 and A=8
so number is
84.48
which also agrees with
all my digit are even 
4.30

I have 1 hundreds 4 ones 2 tens and 1 tenths. What number am i?
