Question

if equals a=3/4 B= -1/2 C =2/3 then find the following i)a+b ii)a+b+c​ iii)a-b iv)a-b-c v) a+b-c​

Answer 1

Answer:

(I) a+b=3/4+(-1/2)=(6-4)/4=2/4=1/2

(ii) a+b+c=3/4+(-1/2)+(2/3)=(9-6+8)/12=11/12

(iii)a-b=3/4-(-1/2)=3/4+1/2=(3+2)/4=5/4

(iv)a-b-c=3/4-(-1/2)-2/3=3/2+1/2-2/3=(9+6-8)/12=7/12

(v)a+b-c=3/4+(-1/2)-2/3=3/4-1/2-2/3=(9-6-8)/12= -5/12
