Question

verify the following rationalnumbers that it an associative property:- -2/5,4/15 and -7/10​

Answer 1

Step-by-step explanation:

Given rational numbers = -2/5, 4/15 and -7/10

-2/5+[4/15+(-7/10)] = -7/10+[-2/5+4/15]

-2/5+[4/15-7/10] = -7/10+[-2/15]

-2/5+[-65/150] = -7/10-2/15

-2/5-65/150 = -7/10-2/15

-125/150 = -125/150
