Question

1supra 2 +2×(25/100+3)​

Answer 1

Răspuns:

$\frac{15}{4}$

Explicație pas cu pas:

$\frac{1}{2} + {2} \times ( \frac{25}{100} + {3})$

$\frac{1}{2} + {2} \times ( \frac{1}{4} + 3)$

amplificam cu 4

$\frac{1}{2} + {2} \times ( \frac{1}{4} + \frac{12}{4} )$

$\frac{1}{2} + {2} \times \frac{13}{4}$

$\frac{1}{2} + \frac{26}{8}$

simplificam 26 supra 8 cu 2

$\frac{1}{2} + \frac{13}{4}$

aplificam 1 supra 2 cu 2

$\frac{2}{4} + \frac{13}{4}$

$\frac{15}{4}$
