Answer: 1, 2, and 3; They are all equivalent fractions
Step-by-step explanation:
A fraction is just comparing an amount of something to the total. In this problem we are looking at which models have the same fractional value of shaded regions to the total regions. Let's do each model.
Model 1 :
6 boxes shaded; 10 boxes total;
Fraction: [tex]\frac{6}{10}[/tex] simplify ⇒ [tex]\frac{3}{5}[/tex]
Model 2 :
3 boxes shaded; 5 boxes total;
Fraction: [tex]\frac{3}{5}[/tex]
Model 3:
3 boxes shaded; 5 boxes total;
Fraction: [tex]\frac{3}{5}[/tex]
Since all models have the same simplified fractional value(we are not looking at size here just proportion), all are equivalent fractions.
That's it!
