Answer:
[tex] \bf \frac{1}{8} [/tex]
Step-by-step explanation:
To calculate what fraction of the whole box she has left, we need to subtract the fraction she ate from the original fraction she had
[tex]\bf Original\ fraction \ \frac{1}{4} (what \ she \ had \ to \ begin \ )[/tex]
[tex]\bf Fraction\ eaten \ is\ \frac{1}{8} \ (half \ of \ \frac{1}{4})[/tex]
so the equation would be
[tex]\large \bf \frac{1}{4}-\frac{1}{8}[/tex]
We need to find the denominator 8 because it is the least common multiple of 4 and 2— the denominators involved. This implies that 8 is the smallest number that can be divided evenly by 4 and 2.
To subtract fractions, you need a common denominator, which is 8
[tex]\large \bf \frac{2}{8} - \frac{1}{8}[/tex]
Now you can subtract this to find the answer
[tex]\large \bf \frac{2}{8} - \frac{1}{8} = \frac{1}{8}[/tex]
So Beth has 1/8 of the box left
