Question

17. Name the property under multiplication used in each of the following:
(i) (3/4) (4/3) = 1
2/5 x (1/5 x 3/5) = (2/5 x 1/5) x 3/5
11/13 x (-5/7) = (-5/7) x 11/13
(iv) 2/3 < (4/7 - 3/5) = (2/3 x 4/7) - (2/3 x 3/5)​

Answer 1

Answer:

Commutative property.

Answer 2

Answer:

(i) (3/4) (4/3) = 1

2/5 x (1/5 x 3/5) = (2/5 x 1/5) x 3/5

11/13 x (-5/7) = (-5/7) x 11/13

(iv) 2/3 < (4/7 - 3/5) = (2/3 x 4/7) - (2/3 x 3/5)
