Question

47/20÷[19/4-4.5×（20%+1/3）]

Answer 1

你这是简算吗？

47/20 ÷ [ 19/4 - 4.5 ×（20%+1/3）]
= 47/20 ÷ [ 19/4 - 4.5 × 20% - 4.5×1/3 ]
= 47/20 ÷ [ 19/4 - 0.9 - 1.5]
= 47 ÷ [20 ×（19/4 - 0.9 - 1.5）]
= 47 ÷ [5 × 19 - 20 × 0.9 - 20 × 1.5]
= 47 ÷ [95 - 18 - 30]
= 47 ÷ 47
=1

Answer 2

47/20÷[19/4-4.5×（20%+1/3）]
=47/20÷(19/4-4.5×20%-4.5×1/3)
=47/20÷(19/4-0.9-1.5)
=47/20÷2.35
=1
