Question

Using distributive property of multiplication, findthe product of the following:(a) 567× 103 (b) 157 x 97(c) 2358 999 + 2358 (d) 103 97(e) 25 x 1001 - 25​

Answer 1

Answer:

(a) 567×103

= 567×(100+3)

= 567×100 + 567×3

= 56700 + 1701

= 58401

(b) 157×97

= 157×(90+7)

= 157×90 + 157×7

= 14130 + 1099

= 15229

(c) 2358×999

= 2358×(1000 - 1)

= 2358×1000 - 2358×1

= 2358000 - 2358

= 2355642

(d) 103×97

= 103×(90+7)

= 103×90 + 103×7

= 10170 + 721

= 10891

(e) 25×1001-25

= 25×(1000+1)-25

= [25×1000 + 25×1] - 25

= [25000 + 25] - 25

= 25025 - 25

= 25000
