Question

c) 60 x (5 sobre 12) - (13 sobre 30 )​

Answer 1

Respuesta:

$60 \times \frac{15}{12} - \frac{13}{30 }$

$\frac{15}{12} - \frac{13}{30} = \frac{(15 \times 30) - (12 \times 13)}{12 \times 30} = \frac{450 - 156}{360} = \frac{294}{360} = \frac{49}{60}$

$60 \times \frac{49}{60} = \frac{60 \times 49}{1 \times 60} = \frac{2940}{60} = 49$
