\bf \cfrac{model}{actual}\qquad 1:300\qquad \cfrac{1}{300}\qquad \qquad \cfrac{3\frac{1}{2}}{a}=\cfrac{1}{300}\implies \cfrac{\frac{3\cdot 2+1}{2}}{a}=\cfrac{1}{300}
\\\\\\
\cfrac{\quad \frac{7}{2}\quad }{a}=\cfrac{1}{300}\implies \cfrac{\quad \frac{7}{2}\cdot 300\quad }{1}=a\implies 1050=a

Avery has 2 blue marbles. One sixth of Avery's marble are blue. How many marbles does Avery have?
katrin [286]

Answer:

Step-by-step explanation:

The equation

2 = (1/6)x represents this situation.

2 is 1/6 of some value.  In this case, the value is the total number of marbles.  2 represents 1/6 of the total number of marbles is how to read that equation in context.  Solve that equation for x

2 = (1/6)x  

12 = x           (multiply both sides by 6 to get rid of the fraction)
