Answer 9

500 + 500 + 500 + ( 100 x 2 ) 

=  500 + 500 + 500 + 200

=  500 x 3 + 200

= 1500 + 200

= 1700

700 + 300 + ( 100 x 10)

= 700 + 300 + 1000

=  1000 + 1000

=   2000

Answer 10

a)       500 + 500 + 500 + ( 100 x 2 ) 

= ( 500 + 500 ) + 500 + ( 100 x  2 ) 

 = 1000 + 500  + 200

= 15000 + 200

= 1700

b) 700 + 300 + ( 100 x 10 ) 

= ( 700 + 300 ) + 1000

= 1000   + 1000

= 2000

Answer 11

\(a,500+500+500+\left(100.2\right)\)

\(=500.3+200\)

\(=1500+200=1700\)

\(b,700+300+\left(100.10\right)\)

\(=1000+1000=2000\)

Answer 12

a) 500 + 500 + 500 + ( 100 x 2 )

=  1500 + 200

= 1700

b) 700 + 300 + ( 100 x 10 ) 

= 1000 + 1000
= 2000

Answer 13

a)     500 + 500 + 500 + ( 100 x 2 )
