Answer 2

原式=9/25×1/6＋1/6×6/25
=1/6×(9/25+6/25)
=1/6×15/25
=1/10

原式=6×1.25×(6×0.25)
=7.5×1.5
=1.5×1.5×0.5
=2.25×0.5
=1.125

Answer 3

1.解：原式=9/25÷6+1×6/25÷6
= （9/25+6/25）×1/6
=3/5×1/6
=1/10
2.解：原式=4×9×0.25×1.25
=4×0.25×（9×1.25）
=1×8×1.25+1.25
=10+1.25
=11.25

Answer 4

1.解：原式=9/25÷6+1÷6×6/25
=9/25×1/6+1/6×6/25
=1/25×1/6(9+6)
=1/25×1/6×15=1/10
36×0.25×1.25
=36×1/4×5/4=45/4

Answer 5

=9/25*1/6+1*1/6*6/25
=1/6*（9/25+6/25）
=1/6*15/25
=1/10
