a)28.4+24-(12+8):2=>52.4-(20):2=>52.4-10=42.4

b)28.4+24-(12+8:2)=>52.4-(12+4)=52.4-16=36

c)28×(4+24-12)=28×(28-12)=28×16=448

d)28x(4+24-12+8)÷2=28×(16+8)÷2=28×24÷2=672÷2=336

e)(28×4+24-12+8)÷2=(112+12+8)÷2=132÷2=66

f)28×(4+24-12+8÷2)=28×(28-12+4)=28×12=336

g)28×(4+24)-(12+8)÷2=28×28-20÷2=784-10=774

h)28-(4+24)-(12+8:2)=28-28-(12+4)=0-16=-16
