4,5+3 2/3=

3,2-1 3/5=

3/7*4,9=

4,8:2 2/5=

6 1/2+2,75=

7,8-5 5/6=

1,5*1 3/5=

3 1/9:1,4=

2 4/5+5,4=

2 3/7 - 1,4=

2,4*2 1/3 =

4,8:6/7=

Answer 1

4.5+ 3 2/3 = 4 3/6 + 3 4/6 = 7 7/6 = 8 1/6

3,2 - 1 3/5 = 3.2-1.6=1.6

3/7*4.9 = 3/7 * 49/10= 2.1

4,8:2 2/5= 24/5 * 5/12 = 2

6 1/2 + 2.75 = 9,25

7.8 - 5 5/6 = 7 24/30 - 5 25/30 = 1 29/30

3 1/9:1.4 = 28/9 * 10/14= 2 2/9

2 4/5 + 5.4 = 2.8+5.4=8.2

2 3/7 - 1.4 = 2 3/7 - 1 4/10 = 2 30/70 - 1 28/70 = 1 2/70 = 1 1/35

2.4*2 1/3 = 24/10 * 7/3 =  5.6

4.8 : 6/7 = 48/10 * 7/6 = 5.6
