Answer 1

a) 3+2*1/5 =3+2/5=(3*5+2)/5=17/5=3,4
b)5-3*1/4=5-3/4=(5*4-3)/4=17/4=4,25
d)0,25:0,5*1/4=0,5*1/4=0,125
e) 1/2+2(0,25+3)=0,5+6,5=7
g) 5/2+3²*0,25=2,5+2,25=4,75
h) 3/4-(2/5)²=3/4-4/25=(3*25-4*4)/100=59/100=0,59
j) 0,75+0,08(3):1/6=0,75+(83-3)/900×6=0,75+75/150=0,75+1/2=0,75+0,5=1,25
k) 0,6+3/5:1,2+1/2*0.4=6/10+3/5×10/12+1/2*4/10=3/5+1/2+1/5=4/5+1/2=13/10
