Answer :

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
