Question

show that - 4 - 3 into bracket 2 by 5 plus minus 7 by 10 equal to minus 4 by 3 into 2 by 5 plus minus 4 by 3 into minus 7 by 10​

Answer 1

-4 -3 × (2/5)+(-7/10) =(-4/3) × 2/5 +(-4/3) × (-7/10)

take l.h.s.

-4-3 × (2/5)+(-7/10)

= -4 -6/5 -7/10

=-4 -19/10

= -59/10

take r.h.s.

-4/3 ×2/5 +(-4/3)×(-7/10)

= -8/15 + 28/30

= 12/30

it is not possible

Answer 2

Step-by-step explanation:

-4/3×(2/5+7/10)=(-4/3×2/5)+(-4/3×-7/10)

Sol:- L.H.S. |. R.H.S

-4/3×(2/5+7/10). | (-4/3×2/5)(-4/3×-7/10)

FIRST OF ALL | = -8/15 + 14/15

TAKE L.C.M. | = L.C.M OF 15 AND 15

OF 5and10. | =15

=10. |. = -8+14/15

= -4/3×(4+7/10). | = -8+14/15

= -4/3×11/10 |= -22/15

= -2/3×11/10. |

= -22/15. |

L.H.S = R.H.S
