Question

Verify that -1/2 +(-4/3+3/7) and (-1/2+3/7)+(-4/3) are the same?

Answer 1

step by step explanation:

-1/2 + (-4/3 + 3/7) = (-1/2 + 3/7) + (-4/3)

by taking out l.c.m

the equation will be like this..

=> -1/2 + (-28 + 9/21) = (-7 + 6/14) -4/3

=> -1/2 + (-19/21) = (-1/14) - 4/3

=> -1/2 -19/21 = -1/14 - 4/3

=> -21 -38/42 = -3 - 56/42

=> -59/42 = -59/52
