Answer 1

a) 2/5+0,3+(0.8-1/2)=0,4+0,3+(0,8-0,5)=0,7+0,3=1

c) (1:0,3-2,1/3)-5/6=(1:3/10-7/3)-5/6=(10/3-7/3)-5/6=1-5/6=1/6

f)6,2/3*(0,25+1/5)=20/3*(1/4+1/5)=20/3*(5/20+4/20)=20/3*9/20=9/3=3

 

a)(5/6+2/6):(8/3-7/4)=7/6:(32/12-21/12)=7/6:11/12=14/11

b)3/2:[(5/4*3/5):6/5]=3/2:[3/4*5/6]=3/2*8/5=12/5

 

a)106/10-14/3+241/15=318/30-140/30+482/30=660/30=22

b)13/2+(10/3-1/2):17/6-7/4=13/2+(20/6-3/6):17/6-7/4=12/3+17/6*6/17-7/4=12/3-7/4=48/12-21/12=27/12=9/4
