Question

Calcule:
9/8 + 7/6 + 1/5

Resposta com a conta

Answer 1

O MMC entre 8,6 e 5 é 120.

$\frac{9}{8} +\frac{7}{6} +\frac{1}{5} =\frac{9.15+7.20+1.24}{120}=\frac{135+140+24}{120} =\frac{299}{120}$

Answer 2

9/8 + 7/6 + 1/5 = (135 + 140 + 24) / 120...........m.m.c.(8, 6, 5) = 120

.................................= 299/120.....(resposta)

8.....6.....5...l 2

4.....3......5..l 2

2.....3......5..l 2

1......3......5..l 3

1.......1......5..l 5

1.......1......1..l........m.m.c = 2 . 2 . 2 . 3 . 5 = 120.
