To find out how many bags of apples Samar has left after using some for pies, we need to subtract the amount of apples he used from the amount he had.
Samar had: \[ 2 \frac{1}{12} \text{ bags} \]
He used: \[ 1 \frac{5}{12} \text{ bags} \]
First, we convert these mixed numbers to improper fractions:
-
Convert \( 2 \frac{1}{12} \): \[ 2 \frac{1}{12} = 2 \times 12 + 1 = \frac{24}{12} + \frac{1}{12} = \frac{25}{12} \]
-
Convert \( 1 \frac{5}{12} \): \[ 1 \frac{5}{12} = 1 \times 12 + 5 = \frac{12}{12} + \frac{5}{12} = \frac{17}{12} \]
Now, we need to subtract \( \frac{17}{12} \) from \( \frac{25}{12} \):
\[ \frac{25}{12} - \frac{17}{12} = \frac{25 - 17}{12} = \frac{8}{12} \]
Now, we simplify \( \frac{8}{12} \): \[ \frac{8}{12} = \frac{2}{3} \text{ (dividing both the numerator and the denominator by 4)} \]
So, Samar has \( \frac{2}{3} \) bags of apples left.
