Question 889879
12.5 + 7.75 = 20.25 acres planted in 2 months.
If {{{1/3}}} acre was destroyed, then 20.25 - .33 = 19.92 acres remaining.
Or did you perhaps mean that {{{1/3}}} *of* the acres was destroyed?
In that case {{{1/3}}} * {{{81/4}}} = 6{{{3/4}}} acres destroyed, leaving 13{{{1/2}}} acres remaining untouched by fire.
