Write your answers in simplest form.
Question 1.
\(\frac{2}{5}\) + \(\frac{2}{5}\) = _____________
Answer:
The denominator of the given fractions are the same. So we have to add the numerators.
\(\frac{2}{5}\) + \(\frac{2}{5}\) = \(\frac{4}{5}\)
Question 2.
\(\frac{1}{3}\) + \(\frac{1}{3}\) = _____________
Answer:
The denominator of the given fractions are the same. So we have to add the numerators.
\(\frac{1}{3}\) + \(\frac{1}{3}\) = \(\frac{2}{3}\)
Question 3.
\(\frac{2}{8}\) + \(\frac{4}{8}\) = ______________
Answer:
The denominator of the given fractions are the same. So we have to add the numerators.
\(\frac{2}{8}\) + \(\frac{4}{8}\) = \(\frac{2+4}{8}\) = \(\frac{6}{8}\) = \(\frac{3}{4}\)
\(\frac{2}{8}\) + \(\frac{4}{8}\) = \(\frac{3}{4}\)
Question 4.
Jeremy and Rosa are solving a math problem. They add \(\frac{1}{3}\) + \(\frac{2}{3}\). Jeremy says the answer is \(\frac{3}{3}\). Rosa says the answer is 1. Who is correct? Why?
Answer:
Given
\(\frac{1}{3}\) + \(\frac{2}{3}\)
The denominator of the given fractions are the same. So we have to add the numerators.
\(\frac{1}{3}\) + \(\frac{2}{3}\) = \(\frac{1+2}{3}\) = \(\frac{3}{3}\) = 1
So, Rosa is correct.
