i)1/2-1/3-(1/4-1/5)

Answer 1

A) 1 3/5-2 1/6=8/5-13/6=48/30-65/30=-17/30
b)3 3/8+2 5/6=27/8+17/6=81/24+68/24=149/24=6 5/24
c)1/2-(-1/6-1/3)=1/2-(-1/6-2/6)=1/2-(-3/6)=1/2+3/6=3/6+3/6=6/6=1
d)7/6+(-5/4-4/3)=7/6+(-15/12-16/12)=7/6-31/12=14/12-31/12=-7/12=-1 5/12
e)-(-2 2/3)+7/15=8/3+7/15=40/15+7/15=47/15=3 2/15
g)1 5/8-(-2 2/3+0,25)=13/8-(-8/3+1/4)=13/8-(-32/12+3/12)=13/8-(-29/12)=13/8+29/12=39/24+58/24=97/24=4 1/24
h)1 2/5-3 7/8-0,125=7/5-31/8-1/8=7/5-30/8=56/40-150/40=-94/40=-2 14/40= -2 7/10
