Find the product by suitable arrangement: (a) 2 x 1768 x 50 (b) 4 x 166 x 25 (c) 8 x 291 x 125 (d) 625 x 279 x 16 (e) 285 x 5 x 60 (f) 125 x 40 x 8 x 25

(a) 2 x 1768 x 50
= (2 x 50) x 1768
= 100 x 1768
= 176800

(b) 4 x 166 x 25
= (4 x 25) x 166
= 100 x 166
= 16600
(c) 8 x 291 x 125
= (8 x 125) x 291
= 1000 x 291
= 291000

(b) 625 x 279 x 16
= (625 x 16) x 279
= 10000 x 279
= 2790000

(e) 285 x 5 x 60
= 284 x (5 x 60)
= 284 x 300
= 85500

(f) 125 x 40 x 8 x 25
= (125 x 8) x (40 x 25)
= 1000 x 1000
= 1000000
