If the denominators are the same, the denominator stays the same. Hint: It is like a reflection in a mirror.  Add the numerators = _ =  Look at the denominator. If the denominators are the same, the denominator stays the same. Hint: It is like a reflection in a mirror. 9 ____________________________________________________________________________________________ _ 6  Subtract the numerators. Chapter 19 Lesson 1,3

15 Copyright ©, Long Beach Unified School District. All rights reserved. - Grade 3 Convert Fractions to Decimals 1. Look at the denominator. Underline the zeros. Chapter 20 Lesson 2 Write this fraction as a decimal __ 52 __. 2. Write the numerator. Starting at the right of the numerator, move to the left underlining the number of spaces that match the number of zeros underlined. 3. Fill in any empty spaces with zeros and add a decimal point. =
