分数四则运算习题
1、直接写得数
=23109÷ 15 -16 = 47 ×1= 12 +17 = 1953
×0= =4375? =7997÷ =3456? =21575÷ =4398? =165÷
=38152019? 13 ×0= 14 × 25 = 56 ×12= 712 × 314 = 45× 35
= 9×718 = 23 × 910 = 425 ×100= 18×16 = 411 × 114
= =1232? 21+5
1= =12165÷ =322÷ 0.82= =8521? =103109- =131020? =98188÷ =7
315÷ =5310? 120÷3÷20= 1-31-3
2= 3.5÷0.07= 27 +35 +57 = 112= 54-(54-21)= 25 ×0×58 = 2.5×7×4= =515+
