Answer 4

25%×132+1/4×8 2)
=1/4×132+1/4×8
=1/4×(132+8)
=1/4×140
=35

32×0.125×25
=(4+8)×0.125×25
=(4×25)×(8×0.125)
=100×1
=1000

75%×76+25×4+0.75×12
=3/4×76+3/4×12+25×4
=3/4×88+100
=166

3200×1/8÷2/5+1270 5)
=400×5/2+1270
=1000+1270
=2270

6×(1/2+2/3)
=6×1/2+6×2/3
=3+4
=7

72.25%×99+75.25%
=75.25%×99+75.25%×1
=75.25%×(99+1)
=75.25%×100
=75.25

2700×（506－499）÷900
=2700×7÷900
=18900÷900
=21 =10

33.02－（148.4－90.85）÷2.5
=33.02－57.55÷2.5
=33.02－23.02

（1÷1－1）÷5.1
=（1－1）÷5.1
=0÷5.1
=0

18.1＋（3－0.299÷0.23）×1
=18.1＋1.7X1
=18.1＋1.7
=19.8
