Answer 1

37X5除36
=（36+1）×5÷36
=（36×5+5)÷36
=5+5/36
=5又36分之5
10500除15除7
=10500÷（15×7)
=10500÷105
=100
（80+8)X125
=80×125+8×125
=10000+1000
=11000
25X32X125
=25×4×8×125
=100×1000
=100000
78.87减42.6减12.27
=36.27-12.27
=24
11分之7除5分之17+11分之4X17分之5
=7/11×5/17+4/11×5/17
=5/17×(7/11+4/11)
=5/17
57X56分之3
=(56+1)×3/56
=3+3/56
=3又56分之3
5.35X34.8+53.5X52%+6X53%
=53.5×3.48+53.5+0.52+5×0.53
=53.5×（3.48+0.52）+5×0.53
=53.5×4+2/10×0.53
=214+0.106
=214.106
