Question

. Verify the associative law of multiplication fo

(i)
2/3,-1/5 and 7/12
​

Answer 1

Step-by-step explanation:

2/3 ( -1/5 × 7/12) = (2/3 × -1/5 ) × 7/12

2/3 (-7 / 60 ) = (-2/15) × 7/12

2/ 3 × -7/60 =-2/15 × 7/12

here 60 will be cancelled by 2 by 30 times and 12 will be cancelled by 2 by 6 times.

-14/90 = -14 / 90

hence, proved.
