1/2+4分之3+7/8加16分之31/十五三十二+64分之63简便计算
1/2+4分之3+7/8加16分之31/十五三十二+64分之63简便计算
1/2+3/4+7/8+15/16+31/32+63/64
=6-(1/2+1/4+1/8+1/16+1/32+1/64)
=6-(1-1/64)
=6-1+1/64
=5又1/64
1/10+4分之3+7/8加15/16+30分之31+60/64计算
1/10+4分之3+7/8 + 15/16+30分之31+60/64
= (1/10 + 31/30)+ (3/4 + 7/8 + 15/16 + 60/64)
= (3/30 + 31/30)+ (48/64 + 56/64 + 60/64+ 60/64)
= 34/30 + 224/64
= 1 + 2/15 + 3+ 1/2
= 4 + 4/30 + 15/30
= 4又30分之19
(16*8分之3+4)/7分之2 简便计算
(16*3/8+4)/(2/7)
=(6+4)*(7/2)
=10*7/2
=35
2分之1/5分之4*(9分之2+8分之3)简便计算
[(1/2)/(4/5)]*[2/9+3/8]
=(1/2)*(2/9)*(5/4)+(1/2)*(3/8)*(5/4)
=(5/4)*(1/9+3/16)
=(5/4)*(16/144+27/144)
=(5/4)*(41/144)
=205/576
简便计算 (24分之7-16分之3)/8分之1
((7/24)-(3/16))/(1/8) = 8*((7/24)-(3/16))=7/3-3/2=14/6-9/6=5/6
(1-3分之1/4分之7)*10分之3简便计算
(1-3分之1/4分之7)*10分之3
=(1-1/3)/(7/4)*3/10=2/3*4/7*3/10=4/35
(0.75-16分之7)÷(3分之2+4分之1) 简便计算
(0.75-16分之7)÷(3分之2+4分之1)
=(9/16-7/16)÷(8/12+3/12)
=1/8÷11/12
=3/44
19分之7*8分之1/28分之21简便计算
(7/19 * 1/8 )/(21/28)
=[7/(19*8)]*(4/3)
=7/(19*6)
=7/114
2/3-6分之1 加1/3-6分之五简便计算
2/3-1/6+1/3-5/6
=(2/3+1/3)-(1/6+5/6)
=1-1
=0
2分之1 / 5分之4 / (9分之2 / 8分之3)用简便计算怎样算呀?
1/2÷4/5÷(2/9÷3/8)
=1/2*5/4÷(2/9*8/3)
=5/8÷16/27
=5/8*27/16
=135/128
