Question

2 (1\4) . 2 (3\4) + 3 (1\2) . 3 (3\2)

Answer 1

$2.\frac{1}{4} . 2.\frac{3}{4} + 3.\frac{1}{2}.3\frac{3}{2} = 4.\frac{3}{16} + 9.\frac{3}{4} = \frac{3}{4} + \frac{27}{4} = \frac{30}{4} = \frac{15}{2}$

Answer 2

2 (1\4) . 2 (3\4) + 3 (1\2) . 3 (3\2) =

(2/4) . (6/4) + (3/2) . ( 9/2) =

(12/4) + (3/2) . (9/2) =

3 + (27/2) =

MMC de 3 e 2 = 6

Logo: (18 + 81) / 6

resposta = 99/6 que é o mesmo que 16,5
