Question

What is another way to write the expression using the Commutative.(1 5/8 + 4 3/4) + 3 2/8

Answer 1

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)

Answer 2

$(1 \frac{5}{8}+4 \frac{3}{4})+3 \frac{2}{8} = \\ \\ ( \frac{13}{8}+ ^{2)}\frac{19}{4})+\frac{26}{8}= \\ \\ \frac{13+38}{8}+ \frac{13}{8}= \\ \\ \frac{64}{8}= \boxed{8}$
