Answer 1

根据题意可得：
6-3/8×X＝0.75
6-0.75＝3/8×X
5.25＝3/8×
X
X＝5.25÷3/8=21/4×8/3=14
从而求出 X＝14

Answer 2

6-3/8×X＝0.75
解6-0.75＝3/8X
5.25＝3/8X
X＝5.25÷3/8
X＝14

Answer 3

6-3/8x=0.75
6-0.375x=0.75
0.375x=6-0.75
0.375x=5.25
x=5.25/0.375
x=14

Answer 4

6－3/8x=0.75
48-3x=6
3x=42
x=42÷3
x=14

Answer 5

6－3/8×20.75
=6－3/8×203/4
=6－3/8×83/4
=6－249/32
=192/32－249/32
=－57/32
