1. Simplify

(a) 11/5+4/21 of 42-18/5 = 27/45.

Solution : 11/5 + 4×42/21 - 18/5 = 27/45.

= 11/5 + 168/21 - 18/5 = 27/45.

= 21×11 + 168×5 /105 -18/5 = 27/45.

= 231 + 840/105 -18/5 = 27/45.

= 1071/105 -18/5 = 27/45.

= [h.c.f of 1071 and 105 is 21.]

= 51/5 - 18/5 = 27/45.

= 51 - 18/5 = 27/45.

= 33/5 = 27/45.

= 33×45 = 5× 27.

= 1485 = 135.

= 1485/135.

= [1485 by 135 is 11.]

= 11. Ans…
