f) 15x+5x
5x

Me ajudem por favor

Answer 1

a) $\frac{3(a-b)}{12}= \frac{1(a-b)}{4} =\frac{a-b}{4}$

b)$\frac{2(x+2y)}{2a} = \frac{x+2y}{a}$

c)$\frac{3(x-1)}{4(x-1)} = \frac{3}{4}$

d) $\frac{5(x+2)}{5.x} =\frac{x+2}{x}$

e)$\frac{8(x-y)}{10(x-y)} = \frac{8}{10} = \frac{4}{5}$

f) $\frac{5x(3+1)}{5x} = \frac{3+1}{1}= 3+1 =4$

Espero ter ajudado. :)
