Question

qual e o calculo de (26/12 . 4/3) +(1/9 . 3/5)

Answer 1

Resposta:

$2\frac{43}{45}$

Explicação passo a passo:

$\left(\frac{26}{12}\cdot \frac{4}{3}\right)+\left(\frac{1}{9}\cdot \frac{3}{5}\right)$

$=\frac{13}{6}\cdot \frac{4}{3}+\frac{1}{9}\cdot \frac{3}{5}$

$=\frac{26}{9}+\frac{1}{9}\cdot \frac{3}{5}$

$=\frac{26}{9}+\frac{1}{15}$

$=\frac{133}{45}$

$=2\frac{43}{45}$

Answer 2

Qual e o calculo de:
(26/12 . 4/3) +(1/9 . 3/5)
= [26/12 (:2)/(:2) . 4/3] + 3/45
= [13/6 . 4/3] + 3/45 (:3)/(:3)
= 52/18 (:2)/(:2) + 1/15
= 26/9 + 1/15
= (5.26+ 3)/45
= (130+3)/45
= 133/45

15,9: 3
5,3: 3
5,1: 5
1,1

= 3^2 . 5
= 9.5
= 45

R.: 133/45
