Question

Am nevoie de ajutor va rog frumos dau coroana!

Answer 1

$1. \: 2.25 \times 1 \frac{3}{5} + 1.(1) \times 4.4 =$

$\frac{225}{100} \times \frac{8}{5} + \frac{10}{9} \times \frac{44}{10}$

$\frac{18}{5} + \frac{44}{9} =$

$\frac{162}{45} + \frac{220}{45} = \frac{382}{45}$

$2. \: \frac{1}{7} = 0.142857$

$3. \: 0.0(384615) = \frac{384615}{9999990}$

$5. \: \frac{47.52}{1.2} = 39.6 \: km \: h$

6. 2,4x + 7 < x + 10,15

1,4x < 3,15 | :1,4

x < 2,25 => x e {0; 1; 2}
