Question

a)-1/8-1/3+2,5+3 1/3 -(-0,125)=
b) 12-2/7-7+ 13 3/7 =
c)- 5 1/8+ 1 1/12+ 2 7/12 +1/8=
d)-0,5-3/4+ 1 1/2-0,25 =

Answer 1

A)= -11/24+2,5+3 1/3-(-0,125)=49/24+10/3-(-0,125)=43/8-(-125/1000)=43/8-(-1/8)=43/8+1/8=11/2=5 1/2
b)= 82/7-7+13 3/7=33/7+94/7=127/7=18 1/7
c)= -41/8+13/12+2 7/12+1/8= -97/24+31/12+1/8= -35/24+1/8= -4/3= -1 1/3
d)= -0,5-0,75+1 1/2-0,25= -1,25+3/2-0,25= -1,25+1,5-0,25=0,25-0,25=0
