Question

[(4/5+5/6×3/25):9/2-1/15]×3 3/4+1/2​

Answer 1

Explicație pas cu pas:

$((\frac{4}{5} + \frac{5}{6} \times \frac{3}{25} ) \div \frac{9}{2} - \frac{1}{15} ) \times 3 \frac{3}{4} + \frac{1}{2} =$

$((\frac{4}{5} + \frac{1}{10} ) \times \frac{2}{9} - \frac{1}{15} ) \times \frac{15}{4} + \frac{1}{2} =$

$( \frac{8 + 1}{10} \times \frac{2}{9} - \frac{1}{15} ) \times \frac{15}{4} + \frac{1}{2} =$

$( \frac{1}{5} - \frac{1}{15} ) \times \frac{15}{4} + \frac{1}{2} =$

$\frac{2}{15} \times \frac{15}{4} + \frac{1}{2} =$

$\frac{1}{2} + \frac{1}{2} = \frac{2}{2} = 1$
