Skraćivanje razlomaka i decimalna vrijednost
Priprema matematičkog prikaza...
(1) Pojednostavi ili proširi razlomke i pretvori ih u decimalne brojeve:
| (a) \( \frac{2}{4 } \) = ________ | (b) \( \frac{20}{40 } \) = ________ | (c) \( \frac{4}{ 60 } \) = ________ | (d) \( \frac{6}{ 210 } \) = ________ |
| (e) \( \frac{35}{70 } \) = ________ | (f) \( \frac{2}{160} \) = ________ | (g) \( \frac{2}{ 240 } \) = ________ | (h) \( \frac{8}{ 35 } \) = ________ |
(2) Skrati razlomke do nesvodljivog oblika, a zatim ih zapiši u obliku decimalnog broja:
| (a) \( \frac{4}{8} \) = ________ | (b) \( \frac{2}{10} \) = ________ | (c) \( \frac{16}{32} \) = ________ | (d) \( \frac{18}{36} \) = ________ |
| (e) \( \frac{2}{8} \) = ________ | (f) \( \frac{4}{40} \) = ________ | (g) \( \frac{32}{64} \) = ________ | (h) \( \frac{12}{60} \) = ________ |
(3) Skratite razlomke (gdje je moguće) i zapišite ih u obliku decimalnog broja:
| (a) \( \frac{4}{200} \) = _______ | (b) \( \frac{ 37 }{800} \) = _______ | (c) \( \frac{120}{100} \) = _______ | (d) \( \frac{6}{300} \) = _______ |
| (e) \( \frac{10 }{400} \) = _______ | (f) \( \frac{4}{600} \) = _______ | (g) \( \frac{112 }{400} \) = _______ | (h) \( \frac{6}{500} \) = _______ |
(4) Upiši u prazna mjesta odgovarajuće razlomke.
| (a) | |
| (b) | |
| (c) | |
| (d) |

(6) Umetnite ispravan simbol (<, =, >).
| \( \frac{8}{64} \) \( \frac{1}{40} \) | \( \frac{8}{14 } \) \( \frac{12}{72} \) | \( \frac{13}{9} \) \( \frac{10}{16 } \) |
| \( \frac{7}{14} \) \( \frac{14}{34} \) | \( \frac{20}{51} \) \( \frac{8}{80} \) | \( \frac{3}{6} \) \( \frac{4}{20} \) |
| \( \frac{12}{48} \) \( \frac{5}{65} \) | \( \frac{15}{68} \) \( \frac{18}{45} \) | \( \frac{4}{1} \) \( \frac{2}{36} \) |
(7) Umetnite ispravan simbol (<, =, >).
| \( 5 + \frac{2}{6} \) \( \frac{9}{18} + 5 \) | \( \frac{5}{9} + 3 \) \( 3 + \frac{6}{8} \) | \( 1 + \frac{7}{14} \) \( \frac{8}{32} + 1 \) |
| \( \frac{1}{5} + 2 \) \( 2 + \frac{4}{12} \) | \( 4 + \frac{10}{15} \) \( \frac{2}{8} + 4 \) | \( \frac{9}{54} + 5 \) \( 5 + \frac{5}{25} \) |
| \( 3 + \frac{6}{9} \) \( \frac{7}{14} + 3 \) | \( \frac{8}{14} + 1 \) \( 1 + \frac{1}{3} \) | \( 2 + \frac{4}{5} \) \( \frac{10}{14} + 2 \) |
