​

Answer 1

$1\frac{5}{7} -4\frac{3}{13} :1\frac{19}{26} =2\frac{4}{9}- ( \frac{46}{63} )$≈073......

округляем выходит 7

$\frac{47}{48} :3\frac{13}{27} -\frac{13}{16} =\frac{855}{1504}- \frac{13}{16} =(\frac{367}{1504} )$≈0.24.....

округляем выходит 24

Answer 2

Объяснение:

№1

1) 4 3/13 : 1 19/26 = 55/13 : 45/26 = 55/13 * 26/45 = 11/1 * 2/9 = 22/9 = 2 4/9

2) 1 5/7 - 2 4/9 = 1 35/63 - 2 28/63 = 1 35/63 - 1 91/63 = -56/63 = -8/9

№2

1) 47/48 : 3 13/27 = 47/48 : 94/27 = 47/48 * 27/94 = 1/16 * 9/2 = 9/32

2) 9/32 - 13/16 = 9/32 - 26/32 = -17/32
