X=7
First, change to improper fractions by:
multiplying whole number by denominator8×6=48
adding the numerator48+5=53 ---- this becomes new numerator
copying the denominator536
so
856 = 536 feet
Do the same for the other fractions.
812 = 172 feet
2413 = 733 feet
536+172 = height of two stories, excluding the attic
Let x = height of attic
x = 733 - (536+172)
Change to similar fractions by getting LCD=6
x = 733(22) - (536+172(33))
x=1466−(536+516)
x=1466−1046
x=426
x=7
