Question

Find the product by suitable rearrangement:
625 x 279 x 16

Answer 1

$\large{\text{(d) 625 x 279 x 16}}$



$\large{\text{= (625 x 16) x 279}}$



$\large{\text{= 10000 x 279}}$



$\large{\textbf{= 2790000}}$

Answer 2

Given : 625 × 279 × 16

To find : Finding the product by suitable rearrangement.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the product by suitable rearrangement)

While rearranging, we need to keep in mind that the rearranged group of numbers should produce any multiple of 10, for the sake of easier calculations.

Similarly,

= 625 × 279 × 16

= (625 × 16) × 279 [Rearranged]

= 10000 × 279 [10000 is a multiple of 10]

= 2790000

(This will be considered as the final result of the given mathematical problem.)

Hence, the answer is 2790000
