简算下列各题：[(5/4-3/8)×5/26+1/8×5/26]÷2又4/13.
简算下列各题：[(5/4-3/8)×5/26+1/8×5/26]÷2又4/13.
简算下列各题：[(5/4-3/8)×5/26+1/8×5/26]÷2又4/13.
：[(5/4-3/8)×5/26+1/8×5/26]÷2又4/13.
=[(5/4-3/8+1/8)×5/26]÷30/13.
=5/26 * 13/30
=1/12
[(5/4-3/8)×5/26+1/8×5/26]÷2又4/13
=(5/4-3/8+1/8)×5/26÷2又4/13
=(5/4-1/4)×5/26×13/29
=5/26×13/29
=5/58
[(5/4-3/8)×5/26+1/8×5/26]÷2又4/13.
=[(5/4-3/8+1/8)×5/26]÷30/13.
=5/26 * 13/30
=1/12
中括号里提5/26 结果为13/30
