Question

if a = 2/5 and b= 7/15, find the value of a- b and b- a. statement weather a- b and b- a are equal or not.​

Answer 1

Answer:

As Below

Step-by-step explanation:

a-b = 2/5 - 7/15 = 6-7/15 = -1/15

While ,

b-a = 7/15 - 1/5 =7-6/15 = 1/15

No a-b and b-a are not equal .

Answer 2

Answer:

a - b = 2/5 - 7/15

        TAKING LCM

a - b = 2 x 3/5 x 3 - 7/15

a - b = 6/15 - 7/15

a - b =  -1/15

NOW,

b - a = 7/15 - 2/5

TAKING LCM

b - a = 7/15 - 2 x 3/5 x 3

b - a = 7/15 - 6/15

b - a = 1/15

THEREFORE, a - b    and    b - a    are not equal
