Answer 1

$(2- \frac{1}{4} )-(3- \frac{1}{2} \\ \\ ( \frac{8}{4} - \frac{1}{4} )-( \frac{6}{2} - \frac{1}{2} ) \\ \\ \frac{7}{4} - \frac{5}{2} \\ \\ \frac{7}{4} - \frac{10}{4} \\ \\ \frac{7-10}{4} \\ \\ \frac{-3}{4}$

Answer 2

Olá, boa noite ☺

Resolução:

(2/1-1/4)-(3/1-1/2)

2/1 - 1/4 - 3/1 + 1/2

m.m.c.(2,4)=4

(8-1-12+2)/4= -3/4
