4又5/8+3又9/16-2又3/4=45/8+57/16-11/4

4又8分之5+3又16分之9-2又4分之3
=4又16分之10+3又16分之9-2又16分12
=(4+3-2)+(16分之10+16分之9-16分12)
=5+16分之7
=5又16分之7
=4又16分之10+3又16分之9-2又16分12
=(4+3-2)+(16分之10+16分之9-16分12)
=5+16分之7
=5又16分之7

4 5/8+3 9/16 –2 3/4
=37/8 + 57/16 - 11/4
=(37x2)+57-(11x4)/16
=(74+57-44)/16
=87/16
=5 7/16
=37/8 + 57/16 - 11/4
=(37x2)+57-(11x4)/16
=(74+57-44)/16
=87/16
=5 7/16
