7. Write in expanded form:

Expanded form is a way to write a number by adding the value of its digits.

(a) 492

Solution: 4 × 100 + 9 × 10 +2 × 1 

400+90+2= 492

(b) 1280

Solution: 1 × 1000 + 2 × 100 + 8 × 10 + 0 × 1 

1000+200+80+0= 1280

(c) 3009

Solution: 3 × 1000 + 0 ×100 + 0 × 10 + 9 × 1

3000+0+0+9= 3009

(d) 8765

Solution: 8 × 1000 + 7 × 100 + 6 × 10 + 5 × 1

8000+700+60+5 = 8765

(e) 9020

Solution: 9 × 1000 + 0 × 100 + 2 ×10 +0 × 1

9000+0+20+0=9020

8. Form the greatest and smallest numbers by using the following  numbers:

To get the greatest number, we

 arrange the digits in descending

 order. To get the smallest number,

 we arrange the digits in ascending

 order.

When forming the smallest number

 where a zero (0) is involved, we

 shift the zero (0) in between the

 first two digits and not placing it at

 the beginning .

(a) 2, 0 , 9

Solution: greatest number: 920

Smallest number: 209

(b) 1, 2 , 3 , 4

Solution: greatest number: 4321

Smallest number: 1234

(c) 5, 6, 1, 2

Solution: greatest number:  6521

Smallest number: 1256

(d) 2, 4, 0 , 9

Solution: greatest number: 9420

Smallest number: 2049

(e) 1, 7, 8, 6

Solution: greatest number: 8761

Smallest number: 1678

9. Follow the pattern and fill in the blanks:

(a) 110 , 210 , 310 , 410 , 510 , 610 , 710
