Question

check if(2/3-(4/5))-1/2=2/3-((-4/5)-1/2)​

Answer 1

Answer:

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

= (10-12/15) -1/2 = 2/3 (-8-5)/10

= -2/15 -1/2 = 2/3 - 13/10

= -4-15/30 = 20 - 39/30

= -19/30 = -19/30

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

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

=(2×5/3×5 - 4×3/5×3) - 1/2 = 2/3 - (-4×2/5×2 - 1×5/2×5)

= (10-12/15) - 1/2 = 2/3 - (-8-5/10)

=-2/15 - 1/2 = 2/3 - -13/10

=-2×2/15×2 - 1×15/2×15 = 2×10/3×10 - (-13×3)/10×3

= -19/30 = 20+39/30 =-19/30 is not equal to 59/30
