1/4+(5/8-3/10)×1/13
=1/4 +(25/40-12/40)×1/13
=1/4+13/40 ×1/13
=10/40 +1/40
=11/40
原式=5/8×4/3+5/8×4/3
=2×(5/8×4/3)
=2×5/6
=5/3
=1/4 +(25/40-12/40)×1/13
=1/4+13/40 ×1/13
=10/40 +1/40
=11/40
原式=5/8×4/3+5/8×4/3
=2×(5/8×4/3)
=2×5/6
=5/3

=5/8×8/3
=1又2/3
=1/4+13/40 ×1/13
=10/40+1/40
=11/40
5/8×4/3+5/8÷3/4
=5/8×(4/3+4/3)
