Answer 1

0.6×1.2= 0.84÷0.6= 4.5×0.1=
15×0.4= 0.1×0.5= 2.8÷7=
100÷0.01= 1.4×3= 0.72÷8=
6÷0.03= 0.5×0.6= 40×0.9=
4÷0.5= 7×2.1= 8.89+0.1=
24×0.25= 0.1÷0.01= 2.4×0.8=
9×0.4= 10×0.01= 30.2-3.02=
4.3-0.25= 1-0.82= 9.6÷0.3=
2.6×0.01= 0×25.4= 4.8×0.4=

Answer 2

=21x5.6-1x5.6
=20x5.6
=112

=18-1.8x1÷0.125÷0.8
=18-1.8x(1÷0.125÷0.8)
=18-1.8x(8÷0.8)
=18-18
=0
