I need help with this pls

3 / 8, 4[ 5 / 12]

Step-by-step explanation:

5 / 8 - 1 / 4

= 5 / 8 - 2 / 8

= 3 / 8

6 [1 / 6] - 1 [3 / 4]

= 6[2 / 12] - 1[9 / 12]

= 4[ 5 / 12]

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
