Представьте смешанное число 2 1/2=1 ?/2 14 5/12=13 ?/12 1 5/8=?/8 9 4/17=8/? 16 3/5=? 8 11/19=?

1) 2 1/2 = 1 (1 + 2)/2 = 1 3/2;

2) 14 5/12 = 13 (5 + 12)/12 = 13 17/12;

3) 1 5/8 = (5 + 1 * 8)/8 = 13/8;

4) 9 4/17 = (17 * 9 + 4)/17 = (153 + 4)/17 = 157/17 = 8/(17 : 19,625) = 8/0,866;

5) 16 3/5 = (16 * 5 + 3)/5 = (80 + 3)/5 =83/5;

6) 8 11/19 = (8 * 19 + 11)/19 = (152 + 11)/19 = 163/19.
