Question

1/2+1/7+5/7? efetue com mmc tambem

Answer 1

Olá!!

Resolução!!

= 1/2 + 1/7 + 5/7

2, 7, 7 | 2
1, 7, 7 | 7
1, 1, 1

2 • 7 = 14

MMC ( 2. 7, 7 ) = 14

14 ÷ 2 = 7 • 1 = 7
14 ÷ 7 = 2 • 1 = 2
14 ÷ 7 = 2 • 5 = 10

= 1/2 + 1/7 + 5/7
= 7/14 + 2/14 + 10/14
= ( 7 + 2 + 10 )/14
= ( 9 + 10 )/14
= 19/14 → resposta

Espero ter ajudado!!
