Упр.52 Вариант 3 Дидактические материалы ГДЗ Мерзляк Полонский 6 класс (Математика)

1) 4 1/12 — 1/6; 3) 5 5/9 — 2 4/7; 5) 8 6/35 — 6 7/10;
2) 9 11/24 — 7 19/36; 4) 9 8/35 — 2 52/105; 6) 9 5/14 — 3 27/49.

1) $$4 \frac{1}{12} — \frac{1}{6} = 3 \frac{13}{12} — \frac{2}{12} = 3 \frac{11}{12}$$

2) $$9 \frac{11}{24} — 7 \frac{19}{36} = 9 \frac{33}{72} — 7 \frac{38}{72} = 8 \frac{105}{72} — 7 \frac{38}{72} = 1 \frac{67}{72}$$

3) $$5 \frac{5}{9} — 2 \frac{4}{7} = 5 \frac{35}{63} — 2 \frac{36}{63} = 4 \frac{98}{63} — 2 \frac{36}{63} = 2 \frac{62}{63}$$

4) $$9 \frac{8}{35} — 2 \frac{52}{105} = 9 \frac{24}{105} — 2 \frac{52}{105} = 8 \frac{129}{105} — 2 \frac{52}{105} = 6 \frac{77}{105} = 6 \frac{11}{15}$$

5) $$8 \frac{6}{35} — 6 \frac{7}{10} = 8 \frac{12}{70} — 6 \frac{49}{70} = 7 \frac{82}{70} — 6 \frac{49}{70} = 1 \frac{33}{70}$$

6) $$9 \frac{5}{14} — 3 \frac{27}{49} = 9 \frac{35}{98} — 3 \frac{54}{98} = 8 \frac{133}{98} — 3 \frac{54}{98} = 5 \frac{79}{98}$$

Ответ

1) $$3 \frac{11}{12}$$; 2) $$1 \frac{67}{72}$$; 3) $$2 \frac{62}{63}$$; 4) $$6 \frac{11}{15}$$; 5) $$1 \frac{33}{70}$$; 6) $$5 \frac{79}{98}$$.
