Question

Julie Drank 1 and 2 3rd cups of cranberry juice.Her brother said she drank 5 3rd cups of juice.Is her brother correct?Explain your answer.

Answer 1

Her brother is correct. He simply changed the mixed number (1 2/3) into an improper fraction. This is done by multiplying the whole number, 1, by the denominator, 3, which gives you 3, and adding it to the numerator, 2. That gives you 5/3.
