Question

Calculeaza: [1,2+1,(3)×3 /20]:0,14×2
Va rog ajutațima dau coroana:*

Answer 1

$(\frac{12}{10} + \frac{12}{9} \times \frac{3}{20}) \div \frac{14}{100} \times 2 = (\frac{12}{10} + \frac{1}{5} ) \div \frac{7}{25} = \frac{14}{10} \times \frac{25}{7} = 5$

Answer 2

[1,2 + 1,(3) × 3/20] : 0,14 × 2 =

= (12/10 + 12/9 × 3/20) : 14/100 × 2

= (6/5 + 1/5) : 7/25

= 7/5 x 25/7

= 5
