0.375乘5又8分之3减8分之3加15.625乘8分之3

解:依题意得算式, 0.625×15分之4 =1000分之625×15分之4 =8分之5×15分之4 =6分之1 即0.625×15分之4=6分之1

0.375就是3/8

0.625×2008+2008×八分之三 =2008×(0.625+3/8) =2008×1 =2008 十五又三分之一÷14 =(14+4/3)÷14 =14÷14+4/3÷14 =1+1/21 =22/21

6592/1088

10-15分之7-0.625-8分之3 =10-(7/15+5/8+3/8) =10-1又7/15 =8又8/15

=(7又8分之3+0.625)-(2.15+4又20分之7) =8-6.5 =1.5

1又9/15*3.3 =(1+9/15)*3.3 =1*3.3+9/15*3.3 =3.3+0.6*3.3 =3.3+1.98 =5.28 2又6/7*0.875 =20/7*7/8 =20/8 =2.5 1又3/5*0.625 =8/5*5/8 =1

0.81+15.3=16.11 1300-497=803 3- 1 2 =2 1 2 3 4 +0.72=1.471÷0.04=25 1 8 ÷0.625= 1 5 4.5× 4 15 = 6 5 1 105 : 1 5 = 1 21 1.5+ 2 3 ×3=3.5 1- 1 3 × 2 5 = 13 15 1.25×0.36×8=3.61÷(2.09-2)= 100 9

8分之5=96分之(60)=10÷(16)=24分之15=0.625=(62.5)%

0.81+15.3=16.11 1300-497=803 3-12=212 34+0.72=1.471÷0.04=25 18÷0.625=15 4.5×415=65 1105:15=1211.5+23×3=3.5 1-13×25=1315 1.25×0.36×8=3.6 1÷(2.09-2)=1009
