The values tell us that the repeated digits give the format ABB.CC.
A is the hundreds digit, B is the tens and ones digit, and C is the tenths and hundredth digit.
Also, A=C+C=2C, B+B=C, so C=2B, and A=2C=4B.
The only available digits are 2, 4, 6, 8.
Therefore B=2, C=4 and A=8 and the number is 822.44.
