Question 5 Solve these using suitable arrangement and properties a) 17 × 108 b) 102 × 103 c) 137 + 908 + 463

Answer 1

a) 17 * 108

17 * (100+8)

1700 + 136

=)1836

b) 102 * 103

(100+2) * (100+3)

100 * (100+3) + 2*(100+3)

(10000+300) + (200+6)

10300 + 206

=)10506

c) 137+908+463

(137+463)+908

600+908

1508

Step-by-step explanation:

1. 17 × 108 {this is called distributive property}

= 17 × (100 + 8) {split the 108 to get 100 + 8}

= (17 × 100) + (17 × 8) {as 17 is outside the brackets we multiply it with everything inside the brackets}

= (1700) + (136) {now we do addition}

= 1836

   2. sorry I'm not sure about this one

   3. 137 + 908 + 463

for this calculation, we use suitable rearrangement

(137 + 463) + 908 {we put 137 and 463 in the bracket because, when we take the ones digit's numbers that is 7 and 3, when we add them both get 10 so that is how you do suitable rearrangement}

(137 + 463) + 908

= (600) + 908

= 1508
