Verified answer

[tex](5 \frac{1}{4} + 3 \frac{3}{4} ) - 4 \frac{2}{17} = 8 \frac{4}{4} - 4 \frac{2}{17} = 9 - 4 \frac{2}{17} =8 \frac{17}{17} - 4 \frac{2}{17} = 4 \frac{15}{17} [/tex]

[tex](19 \frac{3}{19} - 7 \frac{16}{19} ) - (4 \frac{5}{8} + 3 \frac{3}{8} ) = 11 \frac{6}{19} -7 \frac{8}{8} = 11 \frac{6}{19} - 8 = 3 \frac{6}{19} [/tex]

[tex](10 \frac{4}{15} - 2 \frac{11}{15} ) - (1 \frac{6}{11} + 2 \frac{5}{11} ) = 7 \frac{8}{15} - 3 \frac{11}{11} = 7 \frac{8}{15} - 4 = 3 \frac{8}{15} [/tex]

Пошаговое объяснение:

№1

1) 5 1/4 + 3 3/4 = 8 4/4 = 9

2) 9 - 4 2/17 = 8 17/17 - 4 2/17 = 4 15/17

№2

1) 19 3/19 - 7 16/19 = 18 22/19 - 7 16/19 = 11 6/19

2) 4 5/8 + 3 3/8 = 7 8/8 = 8

3) 11 6/19 - 8 = 3 6/19

№3

1) 10 4/15 - 2 11/15 = 9 19/15 - 2 11/15 = 7 8/15

2) 1 6/11 + 2 5/11 = 3 11/11 = 4

3) 7 8/15 - 4 = 3 8/15
