Answer 1

1/3 + 2 + 0,75
1/3 + 2 + 75/100

MMC (3, 2, 100) = 300

100.1/300 + 300.2/300 + 3.75
100/300 + 600/300 + 225/300
925/300 (÷ 25)
=> 37/12

Answer 2

$0,75= \frac{75^{:25}}{100_{:25}} = \frac{3}{4} \\ \\-------------------------\\ \\ \frac{1}{3} +2+0,75= \frac{1}{3} +2+\frac{3}{4}=\frac{4}{12}+\frac{24}{12}+\frac{9}{12}=\frac{4+24+9}{12}=\frac{37}{12}\\ \\-------------------------$

Resposta correta: letra D
