Answer 1

360/450=120/150=40/50=20/25=4/5

500/450=100/90=10/9

280/480=70/120=14/24=7/12

905/60=181/12

Answer 2

a)   360 / 450 = 36 / 45 = 4 / 5

( 360 : 10 )  / ( 450 : 10 ) = ( 36 : 9 ) / ( 45 : 9 ) = 4 / 5

b)   500 / 450 = 50 / 45 = 10 / 9

( 500 : 10 ) / ( 450 : 10 ) = 50 / 45 = ( 50 : 5 ) / ( 45 : 5 ) = 10 / 9

c)   280 / 480 = 28 / 48 = 7 / 12

( 280 : 10 ) / ( 480 : 10 ) = ( 28 : 4 ) / ( 48 : 4 ) = 7 / 12

d)   905 / 60 = ( 905 : 5 ) / ( 60 : 5 ) =  181 / 12
