Question

简算，并写出简算过程。

23-12/17-5/17
44×（5/11+3/4）
7.5×46.7+52.3×7.5+7.5
注意：/=几分之几

Answer 1

23-12/17-5/17
=23-1
=22

44×（5/11+3/4）
=44×5/11+44×3/4
=20+33
=53

7.5×46.7+52.3×7.5+7.5
=7.5×（46.7+52.3+1）
=7.5×100
=750

Answer 2

23-12/17-5/17
=23-（12/17+5/17）
=23-1
=22

44×（5/11+3/4）
=44*5/11+44*3/4
=20+33
=53

7.5×46.7+52.3×7.5+7.5

=7.5*(46.7+52.3+1)
=7.5*100
=750

希望对你有帮助O(∩_∩)O~

Answer 3

解：
1)23-12/17-5/17=23-(12/17+5/17)=23-1=22
2)44×（5/11+3/4）=44×5/11+44×3/4=20+33=53
3)7.5×46.7+52.3×7.5+7.5=7.5×(46.7+52.3+1)=7.5×100=75

Answer 4

23-12/17-5/17=23-(12/17+5/17)=23-1=22
44x(5/11+3/4)=44x5/11+44x3/4=4x5+11x3=20+33=53
7.5x46.7+52.3x7.5+7.5=7.5x(46.7+52.3+1)=7.5x100=750
