Simplify Each. Give each answer as a MIXED NUMBER.

Entry tip: To type a mixed number, put a space after the whole number. To type 123\displaystyle {1}\frac{{2}}{{3}} type "1 2/3" (no quotes)

a) 335÷123=\displaystyle {3}\frac{{3}}{{5}}\div{1}\frac{{2}}{{3}}=  

b) 579−367=\displaystyle {5}\frac{{7}}{{9}}-{3}\frac{{6}}{{7}}=  

c) 623⋅434=\displaystyle {6}\frac{{2}}{{3}}\cdot{4}\frac{{3}}{{4}}=  

d) 578+437=\displaystyle {5}\frac{{7}}{{8}}+{4}\frac{{3}}{{7}}=
