Question

calculati (5supra12-3supra18)×4+1supra11+(4supra3-1)×3​

Answer 1

Explicație pas cu pas:

$( \frac{5}{12} - \frac{3}{18}) \times 4 + \frac{1}{11} + ( \frac{4}{3} - 1) \times 3 \\ ( \frac{5}{12} - \frac{1}{6} ) \times 4 + \frac{1}{11} + ( \frac{4}{3} - \frac{3}{3} ) \times 3 \\ \frac{3}{12} \times 4 + \frac{1}{11} + \frac{1}{3} \times 3 \\ 1 + \frac{1}{11} + 1 \\ 2 + \frac{1}{11} \\ \frac{22}{11} + \frac{1}{11} = \frac{23}{11}$

Answer 2

$(\frac{5}{12} - \frac{3}{18} ) \times 4 + \frac{1}{11} + ( \frac{4}{3} - 1) \times 3 =$

$= (\frac{5}{12} - \frac{1}{6} ) \times 4 + \frac{1}{11} + \frac{4 - 3}{3} \times 3 =$

$= \frac{5 - 2}{12} \times 4 + \frac{1}{11} + \frac{1}{3} \times 3 =$

$= \frac{3}{3} + \frac{1}{11} + 1 =$

$= 1 + \frac{1}{11} + 1 =$

$= 2 + \frac{1}{11} =$

$= \frac{22 + 1}{11} =$

$= \frac{23}{11}$
