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

Solution:

We will be using the associative property of multiplication to find the product of the numbers given below.

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

(b) 4 × 166 × 25
= 4 × 25 × 166
= 100 × 166
= 16600

(c) 8 × 291 × 125
= 8 × 125 × 291
= 1000 × 291
= 291000

(d) 625 × 279 × 16
= 625 × 16 × 279
= 10000 × 279
= 2790000

(e) 285 × 5 × 60
= 285 × 300
= 85500

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