laura finished her history assignment in \\(\frac{3}{4}\\) hours. then she completed her chemistry assignment in \\(\frac{1}{8}\\) hours. how much more time did laura spend on her history assignment?
write your answer as a fraction in simplest form.
\\(\square\\) hours

Explanation:

Step1: Identify the operation

To find how much more time Laura spent on history, subtract the chemistry time from history time: $\frac{3}{4} - \frac{1}{8}$.

Step2: Find a common denominator

The least common denominator of 4 and 8 is 8. Rewrite $\frac{3}{4}$ as $\frac{6}{8}$ (since $4\times2 = 8$ and $3\times2 = 6$).

Step3: Subtract the fractions

Subtract the numerators: $\frac{6}{8} - \frac{1}{8} = \frac{6 - 1}{8} = \frac{5}{8}$.

Answer:

$\frac{5}{8}$
