Answer 1

Salut !

3/4 + 5/4 - 6/4 =

12 /10 - 5/10 +2/10 =

20/100 -15/100+13/100 =

$\frac{3}{4} + \frac{5}{4} - \frac{6}{4} = \frac{8}{4} - \frac{6}{4} = \frac{2(2}{4} = \frac{1}{2} \\ \\ \frac{12}{10} - \frac{5}{10} + \frac{2}{10} = \frac{7}{10} + \frac{2}{10} = \frac{9}{10} \\ \\ \frac{20}{100} - \frac{15}{100} + \frac{13}{100} = \frac{5}{100} + \frac{13}{100} = \frac{18}{100} = 0.18$
