m) 341. 67 +16 .341 + 659 .83
= 341 . ( 67 + 16 ) + 659 . 83
= 341 . 83 + 659 . 83
= 83 . ( 341 + 659 )
= 83 . 1000
= 83000
t) 34 . 62 + 56 . 38 + 22 . 62
= 62 . ( 34 + 22 ) + 56 . 38
= 62 . 56 + 56 . 38
= 56 . ( 62 + 38 )
= 56 . 100
=5600
v) 89 . 33 + 67 . 89 + 100 . 11
= 89 . ( 33 + 67 ) + 100 . 11
= 89 . 100 + 100 . 11
= 100 . ( 89 + 11 )
= 100 . 100
= 10000
q) 24 . 72 + 36 . 28 + 12 . 72
= 72 . ( 24 + 12 ) + 36 . 28
= 72 . 36 + 36 . 28
= 36 . ( 72 + 28 )
= 36 . 100
= 3600
