Answer 1

2,73 + 9 2/3 = 2 73/100 + 9 2/3 = 2 219/300 + 9 200/300 = 12 119/300

 

7/100+10,3 = 7/100 = 10 3/100 = 10 1/10

 

4 5/9+1,5 =  4 5/9 + 1 1/2 = 4 10/18 + 1 9/18 = 6 1/18

 

5 2/5 - 1,25 = 4,2 - 0,4 = 3,8

 

0,9-3/8 = 9/10 - 3/8 = 36/40 - 15/40 = 21/40

 

3,75-1 1/6 = 3 3/4 - 1 1/6 = 3 9/12 - 1 2/12 = 1 7/12

 

1/4 * 1,6 = 0,25 * 1,6 = 0,4

Answer 2

2,73+9 2/3 = 273/100+29/3 = 819/300+2900/300 = 3719/300 = 12 119/300

 

7/100+10,3 = 7/100+1030/100 = 1037/100 = 10,37

 

4 5/9+1,5 = 41/9+ 15/10 = 410/90+135/90 = 545/90 = 6 5/90 = 6 1/18

 

4,2-2/5 = 4,2-0,4 = 3,8

 

5 2/5 - 1,25 = 5,4-1,25 = 4,15

 

0,9-3/8 = 0,9-0,375 = 0,525

 

3,75-1 1/6 = 3 3/4-7/6 = 15/4-7/6 = 45/12-14/12 = 31/12 = 2 7/12

 

1/4 * 1,6 = 0,25*1,6 = 0,4
