(51+2/3)÷(5/3)+(71+3/4)÷(7/4)+(91+4/5)÷(9/5)
=(50+5/3)*(3/5)+(70+7/4)*(4/7)+(90+9/5)*(5/9)
=50*3/5+(5/3)(3/5)+70*4/7+(7/4)*(4/7)+90*5/9+(9/珐功粹嘉诔黄达萎惮联;5)*(5/9)
=30+1+40+1+50+1
=123
=(50+5/3)*(3/5)+(70+7/4)*(4/7)+(90+9/5)*(5/9)
=50*3/5+(5/3)(3/5)+70*4/7+(7/4)*(4/7)+90*5/9+(9/珐功粹嘉诔黄达萎惮联;5)*(5/9)
=30+1+40+1+50+1
=123
