Answer 1

(29 - 6 5/8) - (4 - 5/7) = 22 3/8 - 3 2/7 = 22 21/56 - 3 16/56 = 19 3/28

Answer 2

Ответ:

$19\frac{5}{56}$

Пошаговое объяснение:

$(29-6\frac{5}{8})-(4-\frac{5}{7})=(28+1-(6+\frac{5}{8}))-(3+1-\frac{5}{7})=(28+1-6-\frac{5}{8})-$

$-(3+\frac{7}{7}-\frac{5}{7})=(28-6+\frac{8}{8}-\frac{5}{8})-(3+\frac{7-5}{7})=(22+\frac{8-5}{8})-(3+\frac{2}{7})=22+\frac{3}{8}-$

$-3-\frac{2}{7}=22-3+\frac{3}{8}-\frac{2}{7}=19+\frac{3 \cdot 7}{8 \cdot 7}-\frac{2 \cdot 8}{7 \cdot 8}=19+\frac{21}{56}-\frac{16}{56}=19+\frac{21-16}{56}=19+$

$+\frac{5}{56}=19\frac{5}{56};$
