Question

计算:[6又25分之一减(8.5减16分之三)除以3.5]乘(1又6分之一加3分之一)

Answer 1

[6又25分之一-(8.5-16分之三)÷3.5]X(1又6分之一+3分之一)
=[6+1/25-(17/2-3/16)÷(7/2)]X(1+1/6+1/3)
=[6+1/25-(136/16-3/16)X(2/7)]X(3/2)
=(6+1/25-133/56)X(3/2)
=(6+1/25-2-3/8)X(3/2)
=4X(3/2)+3/50-9/16
=6-(225-24)/400
=6-201/400
=5又400分之199

Answer 2

[6又25分之一减(8.5减16分之三)除以3.5]乘(1又6分之一加3分之一)
=[(6+1/25)-(8.5-3/16)÷3.5]x[(1+1/6)+1/3]
=[(151/25)-(17/2-3/16)÷7/2]x[(7/6)+1/3]
=[(151/25)-(136/16-3/16)÷7/2]x[7/6+2/6]
=[(151/25)-(133/16)÷7/2]x[9/6]
=[(151/25)-(133/16)x2/7]x[3/2]
=[151/25-19/8]x[3/2]
=[1208/1000-475/1000]x[3/2]
=733/1000x3/2
=2199/2000
