Explicação passo-a-passo:

$3{-} \frac{3}{2} \\ \frac{3}{1} - \frac{3}{2} \: (mmc = 2) \\ \frac{6 - 3}{2 } = \frac{3}{2} = 1.5$

Answer 2

$\tt \displaystyle 3-\frac{3}{2}\\\\\\\tt \boxed{\star \ \tt Converta\:para\:fracao:\quad \:3=\frac{3\cdot \:2}{2}}\\\\\\\sf =\frac{3\cdot \:2}{2}-\frac{3}{2}\\\\\\\boxed{\boxed{\tt \star{J\acute{a}\:que\:os\:denominadores\:sao\:iguais,\:combinar\:as\:fracoes}:\quad \frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}}}\\\\\\\tt =\frac{3\cdot \:2-3}{2}\\\\\\\to \large\boxed{\boxed{\boxed{\tt =\frac{3}{2}}}}$
