= 9.95÷4
=10÷4-0.05÷4
=2.5-0.0125
=2.4875
= 7.25除以4+2.7除以4
= (7.25+2.7)除以4
= 9.95÷4

=(10-0.05)*0.25
=2.5-0.0125
=2.4875
=7.25*0.25+2.7*0.25
=(7.25+2.7)*0.25

7.25÷4+2.7x0.25
=7.25x1/4+2.7x0.25
=0.25(7.25+2.7)
=0.25x9.95
=0.25(10-0.05)
=2.5-0.125
=2.4875
=7.25x1/4+2.7x0.25
=0.25(7.25+2.7)
=0.25x9.95
=0.25(10-0.05)
=2.5-0.125
