Question

You eat 3/10 of a pack of hot dogs. Your friend eats 1/5 of the pack of hot dogs. What fraction of the pack of hot dogs do you and your friend eat? Write your answer as a fraction in simplest form

Answer 1

Answer:

  1/2

Step-by-step explanation:

Both fractions can be expressed using a denominator of 10. The sum can be reduced by removing a common factor of 5 from numerator and denominator.

  $\dfrac{3}{10}+\dfrac{1}{5}=\dfrac{3}{10}+\dfrac{2}{10}\\\\=\dfrac{3+2}{10}=\dfrac{5\cdot 1}{5\cdot 2}=\dfrac{1}{2}$
