Answer:
(a) 1/3 of Rs. 45
= 1/3 . 45 [ "dot" represents multiplication]
= Rs. 15 [ Since, 45/3 gives 15 and 15 multiplied by 1 is 15 ]
(b) 3/7 of 4 whole 2/3.
= 3/7 . 14/3
= 2 [ Since, 14/7 gives 2 and 3 gets cancelled on cross-multiplication. So, we are left back with 2 and 1 which on multiplication gives 2 itself ]
Thanks ...!!
