Answer 1

1 5/8 + 0,125 = 13/8 + 125/1000 = 13/8 + 1/8 = 14/8 = 7/4 = 1,75
2 24/25 - 1,46 = 74/25 - 146/100 = 74/25 - 73/50 = 148/50 - 73/50 = 75/50 = 3/2 = 1,5
1/5 *0,75+ 3 = 1/5* 75/100 + 3 = 1/5 * 3/4 + 3 = 3/20 + 3 = 63/20 = 3,15
3 - 1/4 * 5,6 = 3 - 1/4 * 56/10= 3 - 1/4 * 28/5 = 3 - 28/20 = 3 - 7/5 = 8/5 = 1,6
1/14 * 8,4 - 2 = 1/14 * 84/10 - 2 = 1/14 * 42/5 - 2 = 42/70 - 2 = 3/5 - 2 = - 7/5 = -1,4
2 5/6 + 4/9 * 0,375 = 17/6 + 4/9 * 375/1000 = 17/6 + 4/9 * 3/8 = 17/6 + 12/72 = 17/6 + 1/6 = 18/6 = 3
14/15 : 7/3 - 0,5 = 14/15 * 3/7 - 1/2 = 42/105 - 1/2 = 2/5 - 1/2 = - 1/10
0,24: 2/3 + 2 = 24/100 : 2/3 + 2 = 6/25* 3/2 + 2 = 18/50 + 2 = 9/25 + 2 = 0,36 + 2= 2,36
5/12 : 0,25 - 2/3 = 5/12 : 25/100 - 2/3 = 5/12 : 1/4 - 2/3 = 20/12 - 2/3 = 5/3 - 2/3 = 3/3 = 1
14/5 - 0,6 * 2/3 = 14/5 - 6/10 * 2/3 = 14/5 - 3/5 * 2/3 = 14/5 - 6/15 = 14/5 - 2/5 = 12/5 = 2,4
