Answer 1

4 1/15 + 2 1/3 =4 1/15 + 2 5/15 = 6  6/15

4 * 4/10 = 40/10 * 4/10 = 160/100 = 1 60/100

1/14 : 5/4=  1/14 * 4/5 = 4/70
7 : 3/5= 7/1 * 5/3 = 35/3 = 11 2/3
10 - 4/7= 9 7/7 - 4/7 = 9 3/7

24,5 - 12,47= 12,03

241,25 + 12,142= 253,392

5,4 * 0,3= 1,62

4,48 : 0,6= 7,4(6)

(1,2)2= 1,2 * 1,2 = 2,64

Answer 2

4 1/5 + 2 1/3=  4 3/15 + 2 5/15 = 6 8/15

4*4/10= 16/10 = 1 6/10 = 1 3/5

1 /14:5/4= 1/14 * 4/5 = 4/70 = 2/35

7:3/5= 7 * 5/3 = 35/3 = 11 2/3

10-4/7= 9 7/7 - 4/7 = 9 3/7

24,5-12,47=  12,03

241,25+12,142= 253,392

5,4*0,3= 1,62

4,48:0,6= 7,4 (6)

(1,2)2= 1,2 * 1,2 = 1,44
