Answer:

28 non-blue marbles.

Step-by-step explanation:

Initial probability of choosing a blue marble = 4/12

Let the number of non-blue marbles to be added be x.

$\frac{4}{12+x} =\frac{1}{10}$

$12+x=40$ (cross multiply)

$x=28$

A proper fraction is converted to a decimal equivalent by dividing the denominator into the numerator. True

kondaur [170]

False, it's the other way around: you divide the numerator by the denominator.

For example, to evaluate $\frac{8}{15}$ you divide 8 by 15:

$\dfrac{8}{15} = 8\div 15 = 0.5\overline{3}$
