Spectrum Math Grade 5 Chapter 4 Lesson 4.1 Fractions and Division Answers Key
Fractions tell how items are divided. When you see a fraction written like this, \(\frac{1}{3}\) that means something has been divided into 3 parts and the fraction is one of those parts. The division problem 1 ÷ 3, gives the same result.
Read each problem and then answer the questions.
