#-(+1.21)/(+5.6)" "# is the same as:#" "-1xx(1.21/5.6)#
Which will give a negative answer.
So dropping the negative for now.
If the decimals are giving you a problem try this:
#color(green)(1.21/5.5color(red)(xx1) color(white)("dd")=color(white)("dd")1.21/5.5color(red)(xx100/100)color(white)("dd")=color(white)("dd")121/550 )#
#(121-:11)/(550-:11)=11/50#
Hundredths #(1/100)# are part of the decimal system and #2xx50=100# so lets use this.
#(11xx2)/(50xx2)=22/100 = 0.22#
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Don't forget that this is negative
#-11/50" or alternatively "-0.22#
