Final answer:
To determine which glue stick has more, Patti's glue sticks with 1/5 and 3/10 remaining were compared by converting 1/5 to 2/10 so that both fractions had a common denominator. It was found that 3/10 is greater than 2/10, so the glue stick with 3/10 left has more glue.
Step-by-step explanation:
Stressed about fractions? We can easily compare the two partially used glue sticks by converting the fractions to have a common denominator. The fractions representing the amount of glue left in Patti's glue sticks are 1/5 and 3/10. To compare these fractions, we can bring them to the same denominator. Since 10 is a multiple of 5, we can convert 1/5 to the equivalent fraction with a denominator of 10 by multiplying both the numerator and the denominator by 2. Therefore, 1/5 becomes 2/10.
Now, comparing the two fractions 2/10 and 3/10, we can see that 3/10 is larger because they have the same denominator and 3 is greater than 2. Therefore, the glue stick with 3/10 left has more glue than the one with 1/5 (or 2/10).
