计算,能简算的要简算.五又五分之六+4.5-十又三分之一 五分之四×82.2+117又五分之四×0.8
(5-5/1)÷(一又四分之三+2.75) 16/7×(5/3×22+18÷3/5) 4/3÷[8/5-(16/5+0.25)]
答
五又6分之5+4.5-十又三分之一
=10又1/3-10又1/3
=0
五分之四×82.2+117又五分之四×0.8
=4/5×(82.2+117.8)
=4/5×200
=160
(5-5/1)÷(一又四分之三+2.75)
=4.8÷4.5
=16/15
16/7×(5/3×22+18÷3/5)
=16/7×(5/3×22+18×5/3)
=16/7×5/3×(22+18)
=80/21×40
=10.5
4/3÷[8/5-(16/5+0.25)]
=4/3÷[8/5-16/5-4/1]
=4/3÷16/1
=12
