ME AJUDEM TEMA DE MATEMÁTICA!!​

Answer 1

❑ •Olá

a)Exemplo

b)

$7 + \frac{1}{2} = \frac{14 + 1}{2} = \boxed{\boxed{\frac{15}{2} }}$

c)

$\frac{3}{5} + 4 = \frac{3 + 20}{5} = \boxed{\boxed{\frac{23}{5} }}$

d)

$\frac{6}{7} + 1 = \frac{6 + 7}{7} = \boxed{\boxed{\frac{13}{7} }}$

e)

$8 + \frac{7}{9} = \frac{72 + 7}{9} = \boxed{\boxed{\frac{79}{9} }}$

f)

$5 - \frac{3}{4} = \frac{20 - 3}{4} = \boxed{\boxed{\frac{17}{4} }}$

g)

$2 - \frac{1}{2} = \frac{4 - 1}{2} = \boxed{\boxed{\frac{3}{2} }}$

h)

$\frac{7}{2} - 3 = \frac{7 - 6}{2} = \boxed{\boxed{\frac{1}{2} }}$

i)

$\frac{11}{2} - 3 = \frac{11 - 6}{2} = \boxed{\boxed{\frac{5}{2} }}$

j)

$\frac{7}{4} - 1 = \frac{7 - 4}{4} = \boxed{\boxed{\frac{3}{4} }}$

k)

$3 + \frac {1}{4} = \frac{12 + 1}{4} = \boxed{\boxed{\frac{13}{4} }}$
