Answer
$27.141$
Work Step by Step
1. Add the thousandths places. $0.005+0.006 = .011$
2. Add the hundredths places. $0.02+0.01 = 0.03 + 0.011 = 0.041$
3. Add the tenths places. $0.6+0.3+0.2 = 1.1 $
$1.1 + 0.041 = 1.141$
4. Add the whole numbers. $12+8+2+4+1 = 27$
5. Add the decimals back on. $27+.141 = 27.141$
