Question

3/5+(-13/15 + -7/3) = (3/5 + -13/15)+ -7/3..
pls help me up wid b part..​

Answer 1

Answer:

a) x+(y+z) =( x+y) +z

7/3+(-4/5+2/5)=(7/3+[-4/5]) +2/5

7/3+(-4+2/5) =(35-12/15) +2/5

7/3+(-2/5) =(23/15) +2/5

7/3-2/5=23/15+2/5

35-6/15= 23+6/15

29/15=29/15

b) x+(y+z) = (x+y) +z

3/5+(-13/15+[-7/3]) = (3/5+[-13/15]) +(-7/3)

3/5+(13/15-7/5) =(3/5-13/15) -7/3

3/5(-13-35/15) =(9-13/15) -7/3

3/5+(-48/15) =(-4/15) -7/3

3/5-48/15=-4/15-7/3

9-48/15=-4-35/15

-39/15=-39/15
