Question

3 supra 4 × 5 supra 2 + 5 supra 6​

Answer 1

$\frac{3}{4} \times \frac{5}{2} + \frac{5}{6} = \frac{15}{8} + \frac{5}{6} \: \: \: - amplificam \: prima \: fractie \: cu \: 3 \: si \: a \: doua \: cu \: 4 \\ = > \frac{45}{24} + \frac{20}{24} = \frac{65}{24}$

Answer 2

3/4*5/2+5/6

15/8+5/6

15/8 se amplifica cu 3

5/6 se amplifica cu 4

45/24+20/24=65/24
