Question

5 6/13 - 1 11/13 =

у+ 4 8/11 = 10 7/11

Answer 1

1) 5. 6/13 - 1. 11/13 = 3. 8/13

2) у + 4. 8/11 = 10.  7/11
у = 10. 7/11 - 4. 8/11
у = 5. 10/11

Answer 2

$5 \frac{6}{13} - 1 \frac{11}{13} = 4 \frac{19}{13} - 1 \frac{11}{13} = 3 \frac{8}{13}$
у + $4 \frac{8}{11} = 10 \frac{7}{11}$
у = $10 \frac{7}{11} - 4 \frac{8}{11} (9 \frac{18}{11} - 4 \frac{8}{11})$
у = $5 \frac{10}{11}$
