Question

八分之三加六分之五等于四分之三加x脱式计算？

Answer 1

解：解方程，此方程的解为x = 11/24
八分之三加六分之五等于四分之三加x

3/8 + 5/6 = 3/4 + x
（3×3）/（8×3）+（5×4）/（6×4）= 3/4 + x
9/24 + 20/24 = 3/4 + x
29/24 = 3/4 + x
x = 29/24 - 3/4
x = 29/24 - 18/24
x = (29-18)/24
∴x = 11/24
答：此方程的解为x = 11/24

Answer 2

脱式计算：
3/8+5/6=3/4+x
x=3/8+5/6-3/4
x=3/8-6/8+5/6
x=5/6-3/8
x=20/24-9/24
x=11/24

Answer 3

3/8+5/6=3/4+x
解:x=3/8+5/6-3/4
=9/24+20/24-18/24
=(9+20-18)/24
=11/24
