Which has the smallest value?
A:
100−3×20=100−(3×20)=100−60=40 100-3\times20=100-(3\times20)=100-60=40 100−3×20=100−(3×20)=100−60=40
B:
10:5×20=2×20=40 10:5\times20=2\times20=40 10:5×20=2×20=40
C:
50−4×3=50−(4×3)=50−12=38 50-4\times3=50-(4\times3)=50-12=38 50−4×3=50−(4×3)=50−12=38
D':
20:4+10=(20:4)+10=5+10=15 20:4+10=(20:4)+10=5+10=15 20:4+10=(20:4)+10=5+10=15
