а). 0,25 ÷ 4 + 15,3 ÷ 5 + 12,4 ÷ 8 + 0,15 ÷ 30 = 4,6775

1. 0,25 ÷ 4 = 0,0625 ;

2. 15,3 ÷ 5 = 3,06 ;

3. 12,4 ÷ 8 = 1,55;

4. 0,15 ÷ 30 = 0,005;

5. 0,0625 + 3,06 = 3,1225;

6. 3,1225 + 1,55 = 4,6725 ;

7. 4,6725 + 0,005 = 4,6775

б). ( 1,24 + 3,56 ) ÷ 16 = 0,3

1. 1,24 + 3,56 = 4,8

2. 4,8 ÷ 16 = 0,3

в). 2,28 + 3,72 ÷ 12 = 2,59

1. 3,72 ÷ 12 = 0,31

2. 2,28 + 0,31 = 2,59

г).  3,6 + 2,4 ÷ ( 11,71 - 3,71 ) =  3,9

1. 11,71 - 3,71 = 8

2. 2,4 ÷ 8 = 0,3

3. 3,6 + 0,3 = 3,9
