w = width
l = length
w = 1/3 length
l = 7 3/4
w = 1/3 * length
w = 1/3 ( 7 3/4)
change the mixed number to an improper fraction
7 3/4 = (4*7+3)/4 = 31/4
w = 1/3 ( 31/4) = 31/12
12 goes in to 31 2 times with 7 left over
w = 2 7 /12
We need to calculate 7 3/4 * 1/3
First convert 7 3/4 to an improper farction:-
7 3/4 = (4*7) + 3 / 4
= 31/4
So 31/4 * 1/3 = 31/12
= 2 7/12 (answer)
