Question

Q2-Find the following by using distributive property.:

(i).15x6

(ii).17x23

(iii).69x78+22x69​

Answer 1

Answer:

1. 90
2. 391
3. 6900

Step-by-step explanation:

(i)  15x6

    = (10+5)*6

    = (10*6)+(5*6)

    = 60+30

    = 90

(ii) 17x23

    = 17*(20+3)

    = (17*20)+(17*3)

    = 340+51

    = 391

(iii) 69x78+22x69​

    = (69x78)+(22x69​)

    = 69(78+22)

    = 69(100)

    = 6900
