Question

Calcula
a) 9 − 1 3 ∶ [4 + ( 2 10 − 6 5 ) · 12 7 + 5 3 ]
b) 2 5 ∶ 1 10 · (−2) − [( 1 8 − 3 4 ∶ 7 4 ) · 5 3 + 6 11 ]

Answer 1

Respuesta:

a)  $\frac{-166235}{-18472}$

b) $\frac{-627229}{-407}$

Explicación paso a paso:

a)

9-13/ (4+(210-65) x 127+53) =

9-13/ (4+145x127+53) =

9-13/ ( 4+ 18415+53) =

9- 13 / 18471 =

166235 / 18472

(Forma alternativa)

 

8  $\frac{18459}{18472}$ = 8,9993

b)

25 / 110 x (-2) - ((18- 34/74) x 53 +611) =

$\frac{-25}{-110}$ x 2 - (( 18 - $\frac{34}{74}$ ) x 53 +611) =

$\frac{-25}{-55}$ - ( $\frac{649}{37}$ x 53 + 611 ) =

$\frac{-25}{-55}$ - ( $\frac{34397}{37}$  + 611 ) =

$\frac{-5}{-11}$ - $\frac{57004}{37}$ =

$\frac{-627229}{-407}$
