1. 2 1/6 + 3 1/2 - 4 2/5 =
= ( 13/6 + 7/2 ) - 22/5
= ( 13/6 + 21/6 ) - 22/5
= 34/6 - 22/5 = 170/30 - 132/30
= 38/30 = 1 8/30 1 4/5

2.2 1/2 + 1 1/2 × 2 2/3 =
=5/2 + ( 3/2 × 8/3 )
= 5/2 + 24/6
= 15/6 + 24/6
= 39/6
= 6 2/6 6 1/2

1.) 2 1/6 + 3 1/2 - 4 2/5
= 13/6 + 7/2 - 22/5
= 65/30 + 105/30 - 132/30
= 170/30 - 132/30
= 38/30
= 1 8/30
= 1 4/15

2.) 2 1/2 + 1 1/2 × 2 2/3
= 5/2 + 3/2 × 8/3
= 5/2 + 24/6
= 15/6 + 24/6
= 39/6
= 6 3/6
= 6 1/2
