It is important to line up the decimals. Subtract tenths from tenths and hundredths from hundredths.

# 100.47#
#- 98.84#
# 00 1.63#

The hundredths = #7-4= 3 = .03#

The tenths = # 4 - 8 = -4 = -.4 #

Add 10 tenths from the 100 leaving 99. 10 + -.4 = +.6 in the tenths.

The ones now are # 9-8 = 1 = 1.0 in the ones

The tens now are # 9 -9 = 0 = 00.0 in the tens.

so the answer is 01.63
