Question

verify associativity of addition of rational numbers 1/2,4/3 and "-1/5."

Answer 1

Step-by-step explanation:

x = 1 2 12, y = 2 3 23, z = − 1 5 −15 (ii) x = − 2 5 −25, y = 4 3 43, z = − − 7 10 −−710 (iii) x = − 7 11 −711,y = 2 − 5 2−5,z = − − 3 22 −−322 (iv) x = -2, y = 3 5 35,z = − 4 3Read more on Sarthaks.com - https://www.sarthaks.com/1056770/verify-associativity-of-addition-of-rational-numbers-i-e-x-y-z-x-y-z-when-i-x-1-2-y-2-3-z-1-5

Answer 2

Answer:

21/20

1/2 + 3/4 - 1/5

LCM of 2,3,5 = 20

10/20 + 15/20 - 4/20

10+15-4/20

25-4/20

= 21/20
