53 / 210
1 / 2
= ( 1 / 2 ) x ( 315 / 315 )
= ( 1 x 315 ) / ( 2 x 315 )
= 315 / 630
1 / 3
= ( 1 / 3 ) x ( 210 / 210 )
= ( 1 x 210 ) / ( 3 x 210 )
= 210 / 630
7 / 9
= ( 7 / 9 ) x ( 70 / 70 )
= ( 7 x 70 ) / ( 9 x 70 )
= 490 / 630
12 / 35
= ( 12 / 35 ) x ( 18 / 18 )
= ( 12 x 18 ) / ( 35 x 18 )
= 216 / 630
( 1 / 2 ) - ( 1 / 3 ) + ( 7 / 9 ) - ( 12 / 35 )
= ( 315 / 630 ) - ( 210 / 630 ) + ( 490 / 630 )
- ( 216 / 630 )
= ( 315 - 210 + 490 - 216 ) / 630
= ( - 115 + 274 ) / 630
= 159 / 630
= 53 / 210
