we have that
8 3/4 bags
each bag weighs 7 4/5 pounds
step 1
To find out the total weifg, multiply the number of bags by the weigh of each bag
(8 3/4)(7 4/5)
but first
convert mixed number to an improper fractiion
so
8 3/4=8+3/4=35/4
7 4/5=7+4/5=39/5
step 2
substitute
(8 3/4)(7 4/5)=(35/4)(39/5)
=7(39)/4
=273/4
convert to mixed number
273/4=272/4+1/4=68+1/4=68 1/4 pounds
therefore
the total weigh is 68 1/4 pounds
using a graphing tool
the total area is
56+6 2/5+3/5+5 1/4=68 1/4 pounds
