Question

nicoles chemistry textbook weighs 7/8 of a pound and her geometry textbook weighs 1/4 of a pound. how much more does the chemistry textbook weigh than the geometry textbook? write your answer as a fraction or as a whole or mixed number. pounds

Explanation:

Step1: Make common denominators

We need to make the denominator of $\frac{1}{4}$ the same as $\frac{7}{8}$. Since $4\times2 = 8$, we rewrite $\frac{1}{4}$ as $\frac{1\times2}{4\times2}=\frac{2}{8}$.

Step2: Subtract the weights

Subtract the weight of the geometry textbook from the weight of the chemistry textbook. $\frac{7}{8}-\frac{2}{8}=\frac{7 - 2}{8}$.

Step3: Calculate the result

$\frac{7-2}{8}=\frac{5}{8}$.

Answer:

$\frac{5}{8}$
