Question

Să se scrie sub forma de practic: 2,52; 13, 2; 43, 325; 1₁ (6) ; 3, 1(2); 0, (25)) DAU COROANA ​

Answer 1

$2.52 = \frac{252}{100} = \frac{63}{25}$

Simplificam prin 4

$13.2 = \frac{132}{10} = \frac{66}{5}$

Simplificam prin 2

$43.325 = \frac{43 \: 325}{1000} = \frac{1733}{40}$

Simplificam prin 25

$1.(6) = 1 \frac{6}{9} = \frac{1 \times 9 + 6}{9} = \frac{15}{6} = \frac{5}{3}$

Simplificam prin 3

$3.1(2) = 3 \frac{12 - 2}{90} = 3 \frac{10}{90} = 3 \frac{1}{9} = \frac{1}{3}$

Simplificam prin 10 și la final simplifici 3 cu 9.

$0.(25) = \frac{25}{99}$
