By direct multiplication of fractions, we will see that she uses 1/30 of the original container of applesauce to bake the muffins.
Remember that the product of two fractions is just:
[tex]\frac{x}{y} \frac{a}{b} = \frac{x*a}{y*b} [/tex]
Now, we know that Sasha gets 1/3 of the applesauce, and she uses 1/10 of what she gets to make the muffins. So the fraction that she uses is just the product of these two:
[tex]\frac{1}{3}* \frac{1}{10} = \frac{1}{30} [/tex]
This means that she uses 1/30 of the original container of applesauce to bake muffins.
