Answer :
[tex](1 \frac{5}{8}+4 \frac{3}{4})+3 \frac{2}{8} = \\ \\
( \frac{13}{8}+ ^{2)}\frac{19}{4})+\frac{26}{8}= \\ \\
\frac{13+38}{8}+ \frac{13}{8}= \\ \\
\frac{64}{8}= \boxed{8} [/tex]
commutative property of addition is
a+(b+c)=(a+b)+c
so just move the partenthsees ()
(1 5/8+4 3/4)+3 2/8=1 5/8+(4 3/4+3 2/8)
a+(b+c)=(a+b)+c
so just move the partenthsees ()
(1 5/8+4 3/4)+3 2/8=1 5/8+(4 3/4+3 2/8)
