Question

$\frac{7}{8} - (\frac{1}{2} + \frac{1}{3} )$ é pra hoje pfv respondam

Answer 1

Oie, Td Bom?!

= 7/8 - (1/2 + 1/3)

= 7/8 - ([1 . 3]/[2 . 3] + [1 . 2]/[3 . 2])

= 7/8 - (3/6 + 2/6)

= 7/8 - ([3 + 2]/6)

= 7/8 - 5/6

= [7 . 3]/[8 . 3] - [5 . 4]/[6 . 4]

= 21/24 - 20/24

= [21 - 20]/24

= 1/24
