1/3除以(4%5/13%8/13)简便 (0.75%3/16)x(2/9+1/3...

简便计算 1/3÷(4-5/13-8/13) =1/3÷【4-(5/13+8/13)】 =1/3÷【4-1】 =1/3÷3 =1/9 (0.75-3/16)x(2/9+1/3) =9/16×5/9 =5/16

你好: (0.75-3/16)*(2/9+1/3) =(12/16-3/16)×(2/9+3/9) =9/16×5/9 =5/16 45*(7/9+4/15-3/5) =45x7/9+45x4/15-45x3/5 =35+12-27 =47-27 =20

(1) 1 4 ÷(3- 5 13 - 8 13 )= 1 4 ÷[3-( 5 13 + 8 13 )]= 1 4 ÷[3-1]= 1 4 ÷2= 1 8 ;(2)(0.75- 3 16 )×( 2 9 + 1 3 )=( 3 4 - 3 16 )×( 2 9 + 1 3 )= 9 16 × 5 9 = 5 16 .
