Giải đáp:
27/160
Lời giải và giải thích chi tiết:
(1/4+35%+0,75):(5/3+13/3):(1/2+1/5+1/10)×(1/2+1/5-1/10)
=(1/4+7/20+3/4):(5+13)/3:(5/10+2/10+1/10)×(5/10+2/10-1/10)
=(1+7/20):18/3:8/10×6/10
=(20+7)/20:6:4/5×3/5
=27/20×1/6×5/4×3/5
=(27×5×3)/(20×6×4×5)
=27/(20×2×4)
=27/160
(1/4+35%+0,75):(5/3+13/3):(1/2+1/5+1/10)×(1/2+1/5-1/10)
=(1/4+0,35+0,75) : ( 5/3+ 13/3) : (1/2+1/5+1/10) × ( 1/2+1/5-1/10)
=1,35 : 6 : 0,8 ×0,6
=0,225 : 0,8 ×0,6
=0,28124=5 × 0,6
=0,16875
