find the product using suitable property 

a) 999 x 25

999 * 25

(1000 - 1) * 25              (Distributive Property)

(1000 * 25) - (1000 * 1)

25000 - 1000

24000

  • 2

25*999

=25(1000-1)

=25000 - 25 (distributive property)

= 24975

995*25

= 22875

sorry my answer should be

 999 * 25

 25 * 99         (Commutative Property)

 25  (1000 - 1)

 25 * 1000 - 25 * 1

 25000 - 25 (distributive property)

 24975

999*25

(100-1)X25

(25X100)-1

2500-1=2499

 I AM SORRY 

999X25

(1000-1)X25

(25X1000)-1

25000-1=24999

999*25

Here, we can use distributive property i.e. a*(b-c)=(a*b)-(a*c)

as we know that by changing the sequence of the nos. it will not change the product and so we will write it as,

25*999

a*(b-c)

=25*(1000-1)

=24975

(a*b)-(a*c)

=(25*1000)-(25*1)

=25000-25

=24975

Dear friend,
The answer to your query is given below:-
999*25
= (1000-1)*25
= 1000*25-1*25         (Using distributive property)
= 25000-25
Therefore the answer is 24975.
Hope the answer clears all your doubts
