Question

Calculati: 4*(3/4-1/2)+2,5:15/2.

Answer 1

Răspuns:

$= \frac{4}{3}$

Explicație pas cu pas:

$4 \times \Big( \frac{3}{4} - \frac{ {}^{2)} 1}{2} \Big) + 2,5 : \frac{15}{2}$

$= 4 \times \Big( \frac{3}{4} - \frac{2}{4} \Big) + \frac{25 {}^{(5} }{10} \times \frac{2}{15}$

$= \not4 \times \frac{1}{ \not4} + \frac{ \not5}{ \not2} \times \frac{ \not2}{ \not15}$

$= 1 + \frac{1}{3} = \frac{ {}^{3)} 1}{1} + \frac{1}{3} = \frac{3}{3} + \frac{1}{3} = \boxed{\frac{4}{3} }$
