Упр.52 Вариант 1 Дидактические материалы ГДЗ Мерзляк Полонский 6 класс (Математика)

1) 3 1/16 — 1/8; 3) 4 2/7 — 1 4/9; 5) 9 7/9 — 4 5/6;
2) 7 9/20 — 5 17/30; 4) 8 5/36 — 1 43/108; 6) 6 7/32 — 2 11/48.

1) $$3\frac{1}{16}-\frac{1}{8}=2\frac{17}{16}-\frac{2}{16}=2\frac{15}{16}$$

2) $$7\frac{9}{20}-5\frac{17}{30}=7\frac{27}{60}-5\frac{34}{60}=6\frac{87}{60}-5\frac{34}{60}=1\frac{53}{60}$$

3) $$4\frac{2}{7}-1\frac{4}{9}=4\frac{18}{63}-1\frac{28}{63}=3\frac{81}{63}-1\frac{28}{63}=2\frac{53}{63}$$

4) $$8\frac{5}{36}-1\frac{43}{108}=8\frac{15}{108}-1\frac{43}{108}=7\frac{123}{108}-1\frac{43}{108}=6\frac{80}{108}=6\frac{20}{27}$$

5) $$9\frac{7}{9}-4\frac{5}{6}=9\frac{28}{36}-4\frac{30}{36}=8\frac{64}{36}-4\frac{30}{36}=4\frac{34}{36}=4\frac{17}{18}$$

6) $$6\frac{7}{32}-2\frac{11}{48}=6\frac{21}{96}-2\frac{22}{96}=5\frac{117}{96}-2\frac{22}{96}=3\frac{95}{96}$$

Ответ

1) $$2\frac{15}{16}$$; 2) $$1\frac{53}{60}$$; 3) $$2\frac{53}{63}$$; 4) $$6\frac{20}{27}$$; 5) $$4\frac{17}{18}$$; 6) $$3\frac{95}{96}$$.
