Question

find (a-b)-c and a-(b-c) for a=5/4,b=2/3,c=3/2.​

Answer 1

(a-b) -c

(5/4-2/3)-3/2

(20/12-8/12)-3/2

(12/12)-3/2

1/1-3/2

2/2-3/2

-1/2(Answer)

a-(b-c)

5/4-(2/3-3/2)

5/4-(4/6-9/6)

5/4-(-5/6)

5/4+5/6

30/24+20/24

50/24

25/12(Answer)

Answer 2

Answer:

-11/12 , 5/12

Step-by-step explanation:

(a-b)-c

(5/4 - 2/3) - 3/2

LCM = 12 ( a,b )

(15 - 8)/12 - 3/2

7/12 - 3/2

LCM = 24

(14 - 36) / 24

-22/24 = -11/12

a-(b-c)

5/4 - (2/3 - 3/2)

LCM = 6

5/4 - (4 - 9)/ 6

5/4 - (-5/6)

5/4 + 5/6

LCM = 12

( 15 - 10)/12

5/12
