в последнем 5 ц 2/44 или 52/44? не пойму

Answer 1

4 7/27 - 2 2/9=4 7/27 - 2 6/27=6 1/27

6 11/48+17/24=6 11/48+34/48=6 35/48

7 61/81 - 1/18=7 122/162 - 9/162=7 113/162

0,625+6 9/16=625/1000+6 9/16=5/8+6 9/16=10/16+6 9/16=6 19/16=7 3/16

7,8+39/50=7,8+0,78=8,58

2/11+7/22+5 2/44=4/22+7/22+5 1/22=5 12/22=5 6/11
или
2/11+7/22+52/44=4/22+7/22+26/22=37/22=1 15/22
