(ii) 5/3-7/6+(-2/3)
(iii) -3/2+(5/4-7/4)​

Answer 1

(I) 1/6

(I) 1/6(ii) -1/6

(I) 1/6(ii) -1/6(iii) -2

(I) 1/6(ii) -1/6(iii) -2Step-by-step explanation:

(I) 1/6(ii) -1/6(iii) -2Step-by-step explanation:(I) -2/5-(-3/10)-(-4/15)

(I) 1/6(ii) -1/6(iii) -2Step-by-step explanation:(I) -2/5-(-3/10)-(-4/15)LCM of 5,10,15=30

(I) 1/6(ii) -1/6(iii) -2Step-by-step explanation:(I) -2/5-(-3/10)-(-4/15)LCM of 5,10,15=30-2/5×6/6=-12/30

(I) 1/6(ii) -1/6(iii) -2Step-by-step explanation:(I) -2/5-(-3/10)-(-4/15)LCM of 5,10,15=30-2/5×6/6=-12/30+3/10×3/3=9/30

(I) 1/6(ii) -1/6(iii) -2Step-by-step explanation:(I) -2/5-(-3/10)-(-4/15)LCM of 5,10,15=30-2/5×6/6=-12/30+3/10×3/3=9/30+4/15×2/2=8/30

(I) 1/6(ii) -1/6(iii) -2Step-by-step explanation:(I) -2/5-(-3/10)-(-4/15)LCM of 5,10,15=30-2/5×6/6=-12/30+3/10×3/3=9/30+4/15×2/2=8/30So,-12/30+9/30+8/30

(I) 1/6(ii) -1/6(iii) -2Step-by-step explanation:(I) -2/5-(-3/10)-(-4/15)LCM of 5,10,15=30-2/5×6/6=-12/30+3/10×3/3=9/30+4/15×2/2=8/30So,-12/30+9/30+8/30=5/30=1/6 ans.

-7/6×1/1=-7/6

-7/6×1/1=-7/6-2/3×2/2=-4/6

-7/6×1/1=-7/6-2/3×2/2=-4/6So,10/6-7/6-4/6

-7/6×1/1=-7/6-2/3×2/2=-4/6So,10/6-7/6-4/6=-1/6 ans.

-7/6×1/1=-7/6-2/3×2/2=-4/6So,10/6-7/6-4/6=-1/6 ans.(iii) -3/2+(5/4-7/4)

-7/6×1/1=-7/6-2/3×2/2=-4/6So,10/6-7/6-4/6=-1/6 ans.(iii) -3/2+(5/4-7/4)5/4-7/4=-2/4

-7/6×1/1=-7/6-2/3×2/2=-4/6So,10/6-7/6-4/6=-1/6 ans.(iii) -3/2+(5/4-7/4)5/4-7/4=-2/4=-1/2

-7/6×1/1=-7/6-2/3×2/2=-4/6So,10/6-7/6-4/6=-1/6 ans.(iii) -3/2+(5/4-7/4)5/4-7/4=-2/4=-1/2So,-3/2-1/2=-4/2

-7/6×1/1=-7/6-2/3×2/2=-4/6So,10/6-7/6-4/6=-1/6 ans.(iii) -3/2+(5/4-7/4)5/4-7/4=-2/4=-1/2So,-3/2-1/2=-4/2=-2 ans.
